We frequently let people have copies of 'Heslop' songs by keeping 2 or 3 A4's with dots in the camper van. If you run out you can always take an address and post it on to them. If they don't read dots you can always volunteer to sing it onto a tape/cd /mindisc or whatever (Cylinder if you like!.) But.. I would really impress on you that you should make sure they are all copyrighted before you give them out. If you are a member of MCPS /PRS so much the better as if they are recorded / sung / played publicly then you get the credit for your own work. Money doesn't really come into it unless someone really big is going to record one of them so no jibes, please, about money. Songwriters get pence per 1,000 of tracks unlike the artists and big record companies. A friend of ours once got 5p for the karioake version of one of his songs!
If you don't know how to copyright them give Jon a ring and he'll help.
