Yeah i like the stuff from that period. Unpolished, straight rock, even with some hints of punk. Unfortunately, the bands had to "play nice" when recording stuff.
Most of the stuff I like is pre-epstein, who, IMHO, had a not so positive effect on the Mersey beat. Just compare how lads were playing in hamburg and after that.

I like elton too. I like his early stuff and a live recording with lennon at MSG.
Im sure Im gonna have great time there:)
