Maureen, if you copy the link for the YT video and paste it here, you can make download it as an mp3.
You can also probably buy an mp3 of the song for $1 on iTunes.

Jim,
The only minor correction I would make to the lyrics you posted is that, at least in the Sammy Kaye hit recording, they sing:

"I hope my story don't make you cry,
But this birdie flew too high ...

It's minor, but not only do they sing it that way, "birdie" scans better than "bird." "Birdie" is also sung in the 2nd verse.
