the song Madelaine sang on SNL

What was the name of that song.
Madelaine Kane sang it on the opening of a SNL.
It was really good and she did a high voice and a real low one for the next lines.
Anyone?

lonely frog

who was it originally by?
Could I get it anywhere?

sorry- not the actual title- just clarifying the song you were referring to-

the title is " Ain’t Got No Home"

Google search - original author is in question- but I have the episode on videotape- have loved her since “Blazing Saddles” - funny, and what a voice. Sad she’s gone-
