Well, the beatles were the starting point and inspiration to many bands,you could say there were the best and still are since i doubt there is someone that does not know a song or at least their name.Their live shows weren?t incredible though, you may think because of the time and tech but we have the example of many like The Rolling Stones or Pink Floyd, i think floyd not only managed to beat everyone (referring to live shows and presentations), they were even vote the best band in live 8 after a 20 year break-up, they came toghether to sing , wich ringo and paul didn?t.
