Thanks for your feedback. And thanks for the paragraph on the back of each one...it's clear you gave this some thought.
As to the content:
1) Cocaine: I prefer the original version...perhaps only because I'm a bass player, and it takes more than one hand to count the errors in the recording by the bassist. Obviously they were playing with a "little helper" from the title track!
2) Beatles: Gotta have something from them in there somewhere. Actually, "Hey Jude" is a superb choice; debating that with "Lucy" and the medley from the back side of Abbey Road.
3) My Generation. On the bubble. What's better, in you opinion, as the "starting" point for Rock: My Generation or the Kingsmen's "Louie Louie"?
4) Purple haze. Fine, but eclipsed by "Watchtower", IMHO
