That's great that you can get a group of youngsters like that interested in The Beatles and The Stones.
Beatles songs can be tough. On the surface they seem simple, but once you dig in...not so much, especially with the harmonies.
I'm sure your local music shop LOVES you!!! :-).
That's so cool! My kids are still young (5, 7 and 10). My 10 year old isn't interested in my music as much as I've tried to get her involved. I still have hope with my 5 and 7 years olds...
I look forward to hearing how it goes. If you record the show, post links so we can all have a listen!! I'm sure it would go over well.
