"Memphis Melody"
Cut Scenes:

The first version of the script was called simply Elvis.

In it, Sue Anne was called Mary Lou.

The squealing pig act is instead a pair of hillbillies.

Al admits the Project team assumed an Elvis impersonator had leaped into the Waiting Room.

Elvis also gives instructions to Sam from there via Al: "Elvis says you have to sing because he missed the last two rehearsals, and if you don't sing, they'll kick him off the program".

The reference to being "shook up" in the diner has yet to be added, along with the hologram apple pie gag.

Sue Anne says "when I sing Amazing Grace sometimes I feel I can near touch heaven", prompting Sam to suggest she sings (in the transmitted version, it's Sam's choice of song).

There's a little extra discussion between Sam and Elvis's mother, as Sam promises her he'll do her and daddy proud and later he explains to her about the Christmas carols getting him an audition.

Right before Sam sings at Sun Records for the first time, Elvis had been performing the same songs for the Project staff and Tina was begging for an encore.

Sam pushing at Marion to play the record for Mr Phillips goes on longer, with her eventually telling him "I'll play it for him, soon as I hear reindeer on the roof".

After Sam and Frank fight, Frank plays up his injuries more, bravely offering to try to walk.

Sam convinces Sue Anne to try and audition much more quickly, just saying "I don't care what you think about me. You don't have to talk to me ever again. But don't be afraid to dream" - it's a much longer piece in the finished script.

Sam tries to get ideas on which song to choose from Elvis during the audition, demanding of Al "Ask Elvis! You've got him in the Waiting Room!" (Al points out "he hasn't sung them yet!")

The change of history is a bit restructured and we learn that Heartbreak Hotel is sung by Barry Manilow.

There's a moment reminiscent of Back to the Future where a little girl hears Sam singing in the diner and holds a phone up saying "Just listen, Daddy! He's singin' about playin' house!" - it doesn't make much sense in itself, although later (including in the transmitted version) Al says "you've inspired someone to write one of his first hits" - could the girl be the daughter of Arthur Gunter, who wrote that song in 1954?
