You're quite welcome! I'm confident you'll enjoy it. It's a pretty fun score.
As for what John Barry was thinking, he was actually the second choice. Initially, they wanted Thomas Dolby to do the score too, but it turned out to not be a good fit. Here's a sneak peak at page 8 of the liner notes:
JOHN BARRY:"They gave me a last-minute call to do it, and I thought it would be exciting to work with George Lucas."
Having heard this score...I'm glad Barry made that mistake!
