The Complete Million Dollar Session, as released on the Charly label (CDCRH 123 -released in 1997, Germany) is pretty complete, as the title claims.
On all Million Dollar releases small fragments are missing: Reconsider Baby f.i. and parts of "Don't Forbid Me / You Belong To My Heart". And perhaps there's more missing that we still don't know was recorded.
But don't let these missing parts put you off. The recordings are still worth getting!
What other chance would one get to hear Jerry Lee Lewis, Carl Perkins and Elvis jam together?
But if you're looking for these recordings i.m.o. the Charly release is the one to search for.
Hope this helps,
