Sing-along songs?

[juman]

Say that it's late and you are at a party with good friends, or it's summer and you are at a barbecue and someone brings out a guitar. What are the songs in your language that are guaranteed that people will sing along to? This can of course go for other situations as well (christmas, birthdays etc) where there is a friendly atmosphere and even though people might not say that it is the music they prefer but they are guaranteed to know anyway.

Being from Sweden I'll start off with some Swedish classics but please add your own (I'm mostly curious about French, Esperanto and German) :

Tomas Ledin - a really famous sommersong writer here in Sweden
Sommaren är kort - https://www.youtube.com/watch?v=wlhY1WEAH8U
Inatt är jag din - https://www.youtube.com/watch?v=I8Ub3zAXci8
En del av mitt hjärta - https://www.youtube.com/watch?v=WJX5X_0hKU8

Some classics (so called dansbandsmusik):
Eloise - https://www.youtube.com/watch?v=vLtGZVZs32s
Jag vill vara din Margareta - https://www.youtube.com/watch?v=TNDlkeBuPJU

Some 80ies :
Vill ha dig i mörkret hos mig - https://www.youtube.com/watch?v=aOXw9Vfz14I
OOa hela natten - https://www.youtube.com/watch?v=ZWByXDB0IKw
Sommar tider - https://www.youtube.com/watch?v=beFPoiNn0Bs

Another famous songwriter Ulf Lundell
Jag trivs bästa i öppna landskap - https://www.youtube.com/watch?v=uuOUev9EgI8

Misc :
Ta mig till havet - https://www.youtube.com/watch?v=gM3N67a-x1U

Great idea for a thread! I'll throw out some suggestions for Russian.

Rock music: Kino is probably the most iconic Russian rock band, at least by the criterion of recognition among the general audience outside rock fans; a lot of people only know of its frontman, Viktor Tsoi.
Звезда по имени солнце
Группа крови
The above two songs are pretty much universally known. Depending on the company you're with people might be able to recognize more of their songs. The next two seem to be particularly popular at gatherings:
Пачка сигарет
Видели ночь; People of my generation (now in their mid-20s) might be more familiar with the more upbeat version by Zdob și Zdub.
Other rock bands/artists:
Mashina Vremeni - Поворот
Akvarium - Город Золотой
DDT - Что такое осень (a song arguably more popular among the "casual" audience than among the band's actual fanbase)
Kipelov - Я свободен
Grazhdanskaya Oborona - Все идет по плану; A somewhat cautious recommendation. My father, while a fan of Russian rock, apparently isn't aware of either the song or the band, but one time when I went camping with people in their late 20s there were three guitarists among us and this was the only song we all knew how to play (and when we started playing and singing, people from the opposite side of the lake joined in). Might not be appropriate for some gatherings due to the strong language; also not advisable to start debates about the song's meaning.

Bard music/"authors' song" - a musical current of independent singer-songwriters that originated in the Soviet times. A lot of the songs have an escapist undertone and many deal with the subject of travelling. Generally obscure among those too young to remember the Soviet days, aside from a handful of artists and songs.
Oleg Mityaev - Как здорово (Изгиб гитары желтой...): The quintessential campfire song.
Yuri Vizbor - Милая моя
Нам нужна одна победа: only really counts as a "bard" song since it was technically written by one, but otherwise it's fairly mainstream; one of the best known songs about WW2, often sung at Victory Day celebrations.

Others:
Песня друзей; a song from a popular cartoon and another staple for campfires and general gatherings.
Пусть бегут неуклюже; another cartoon song and a popular alternative to "Happy Birthday to You".
Katyusha; a wartime classic, but not necessarily sung just at Victory Day celebrations.
Песня про зайцев; from a beloved Soviet comedy, now a popular drinking song.

Also, since I grew up in Kazakhstan I should probably also mention something for Kazakh. While I'm not terribly familiar with the Kazakh music scene, it seems like nearly all Kazakhs, no matter how Russified, can sing along to Көзімнің қарасы.

For Esperanto I would say that the absolute classic is 'Sola'. I think it would be hard to find a young person who had been to an international Esperanto event and didn't identify with this song emotionally and wasn't prepared to at least sing along to the chorus



The song is so iconic that there is even a parody version (lyrics NSFW but very funny!).



Otherwise I would say that a song everyone probably knows, even if they don't normally like that kind of music, is 'Ska-virino'.

The first song which popped into my head for Spanish was Un beso y una flor by Nino Bravo. It's a real karaoke number In fact, I first came across the song while watching the karaoke scene at the end of the film Al final del camino.
