'Heartbreaker' Improv Question

[Stairway is NOT stolen]

Hi all.

I've been listening to the Heartbreaker Improv that Jimmy does on the 'How the West was Won' Album. I have a question.

During Jimmy's improv, he does this little tune that I have heard before, but I don't know what it is. On the HTWWW album, the bit I'm talking about is at 4:42. Any help would be appreciated.

Thanks
