Sorry if something like this has been done before- but I thought it would be interesting to hear of some Beatles 'firsts' no matter what they are. They were so influential and had so many 'firsts' from music, to lifestyles, to beliefs :-)
I guess I will start then...
- the first band to use a sitar on their records (more groups used sitars later following their example- e.g. the rolling stones)
so what else is there? ...
