>> larry: everything that happens has to fit the song that happens. >> normally we build our show and the music would follow in support. now we had to work on the music. so basically what we've done, i went to london working with george martin and giles, martin's son. >> we took the masters, digitized them, brought them to vegas, and produced the music for the show in a way that we are replicating everything that was heard and wrote. what we have here on the master tapes. >> larry: can we sea some sounds? >> yeah. this is the very beginning mix. the drums you are hearing here are actually from another song -- from the end of abbey road. and what you'll get is "get back" the start of a song underneath it. so these are two songs.
