I agree with the last poster - there is a vibrant musical scene in London and H counties at least which has separate circuits from the Folk club listings. There are blues and country music clubs - jazz and swing - acoustic and world music clubs where younger age ranges foregather and play

Also a lot more is done online and via social networking

I am old - so I am not going to get involved in making judgements about younger people but I am involved in flamenco - jazz - blues - folk - classical and acoustic music
Also in my part of London there are lots of gospel and soul related choirs with lots of young people actively involved
