"Penny Lane" analysis

[Ted]

This is one of my favorite performances by Elvis Costello – and that's saying something. I'm a big EC fan.

And I love this story. I hope it's true:

As originally planned, the trumpet solo was to be performed on a keyboard.  Then, seeing that the Marine Corps band was present, Elvis approached the trumpet player and asked, "If I gave you this sheet music, could you play the trumpet part without a rehearsal?"  The Marine looked down at Elvis.  Elvis said, "I'll take that as a 'Yes'."
