Well, if you click here or click here, you might be able to transcribe it from a clip from The Simpsons. You can do further research on this by going to www.hotbot.com and searching under "spanish flea simpsons."
Here's what I could make of it. Sorry, but Homer's diction isn't all that good, and I can't understand it completely. This may be as close as you're gonna get. Music was written by Julius Wechter in 1966. The words are no doubt written by those wonderful people who bring you The Simpsons.

There was a little Spanish flea
A record star he thought he'd be
He heard of singers like Beatles
The Chipmunks he'd seen on TV,
Why not a little Spanish flea?
