Hi, Branwen, welcome to the Mudcat. The song you are looking for is in the database, and is called "MAGGIE". To access the database enter a search word or words in the blue box upper right and all the songs with those words in them will appear. I used "Maggie" and got maybe 20 songs, one of them being the one you want. Or if you want to be lazy, just click here.
Blessings,
Barbara
