What is the birthday song in your country ? Everyday life and customs

I forgot to mation another joke: a parody of "Bon anniversaire, nos vœux les plus sincères" which is "C'est ton anniversaire, c'est pas celui d'ta mère" which means, "it's your birthday, not your mother's".

My favourite birthday song is a comedy song from the time... beginning of the 80's - which was really played again and again on birthday parties that time... and as I was a little rug rat I loved it... and still do so today 😃

it is not customary for us to sing birthday songs, but if you celebrate in a karaoke bar, then it is accepted. but personally, I like it when a song is sung about a hero with the same name as the birthday boy. this is also a good gift in its own way)))
