I dont know if you enjoy singing , but in many countries here in Europe, there are lots of choirs for all types of music, as well as for beginners, for almost professionals and usually all ages mixed or lots of people above 40. Usually people go for a drink after rehearsal but not for the alcohol but for the company. In my choir many that come to the bar after rehearsal just drink something nonalcoholic.
Here, 40 is also an age where people still go to bars without feeling weird about it. Of course there are a few bars only full of Students but there are still lots of bars with people above 40 too.
I thought so, and also because of that try not to buy overseas and generally buy second Hand and local, but still its terrible to hear that it is indeed this way. :/
