Zepplin is far too EPIC to be contained by plastic instruments. Plastic does not hold the fortitude for Achilles last stand, can your console sync with a guitar ORCHESTRA? Can you imagine the set list? You though 5 four minute songs were bad? 5 ten minute jams? Inconceivable!

Also, weren't the beatles a far more successful studio band? These games normally show concerts, a live situation, sure the early beatles stuff works in that context, but some of the later stuff uses the studio as an instrument. How are they gonna illustrate that? Plus I feel that the 4 instrument setup sort of fails to capture what mimicking the beatles would be like. Pianos and keyboards become fairly prevalent, among string arrangements, in addition to the always present vocal harmonies, and playing a sitar is nothing like playing a guitar. Not to mention it's gonna get pretty boring "playing ringo"

. I'd say that this game has some pretty big boots to fit into!
p.s. top 3 beatles albums 1.Magical Mystery Tour (reminds me of earthbound) 2.Abbey Rd (The second half is the greatest thing to come from rock music) 3. Rubber Soul (nice stark mixing)
p.s.s it'd be pretty easy to get a couple of acoustic guitars and a drum set and learn all these songs too, nothing too hard!
