To add to my previous post,tourists can also be musicians,only two weeks ago, the addition of tourist/musicians to my gig was a plus.
Only last saturday,I took part in an impromptu session,in a local pub,we were playing for our own pleasure[no money involved]all the other musicians were musicians who play gigs for money[so are part of the tourist industry],we played the same repertoire,as we would for a paid gig.
I have also found mobile phones a useful way to pass on music/tunes orally to teenagers,who want to learn a particular tune.
