I'm also thinking that if #64 had a gray circle behind it, and the font over top like #62, it might be a winner.
Should those changes be installed on #64, I think the whole perspective aspect of #62 would be lost. #62 is good because of the perspective of the guy to the drum and plastering a logo across him would eliminate the effect.
#69 & #70 have the same relationship. I like them better and lean more toward #70. If the background tone was lightened about three shades, it would work pretty well.
One problem I see with the whole body shot, giving the perspective, is that when that gets shrunk to be put onto items, especially small stuff, it will become visually confusing. Unless a brilliant color are used and a custom created color at that, ala Westinghouse blue, then the logo will not register with the target audience. I think the half body works better.
However, I think the current logo works very well for these stated reasons.
