two interesting studio trax are "Hold Me Tight" (definitely a different take than the WTB one), and the piano-less (it sounds to me, anyway) "Money." The vocals sound like the final take ones (unless John and Paul were THAT good at duplicating their voices!), but the song sounds harder, edgier (maybe because of the lack of-- or very low levels of-- piano?).
Some of the live BBC stuff is great, too...different than the two compilations...a few "Roll Over Beethovens" but one, in particular, has George doing an extended guitar solo-- the only time (other than maybe the Star Club-- and I can't recall that album that well as I haven't heard it in ages) I've ever heard that.
