You guys are aware that there is a long studio version, right? It's what the album version was edited down from. It was the B-side of the 12-inch single and (later) CD single of "Mama" (the long version that fades out some 40 seconds later than the album version).
To me, the long versions of these two songs are the real versions, and the album versions are just inessential extras.
I am aware and have the Mama CD single for that reason, but I acquired that much more recently so the edited album version is the one I listened to for many years. So my opinion of the song is based more on it than on the full version.
