I once heard the long version of "With A Little Luck," and I was like c'mon already!!! Finish with that nice little duuuu-duh!
So I guess that, since I was brought up with the short versions, that I'm a short singles kind of guy. But that's not written in stone.
I grew up always hearing Tommy James & The Shondells short version of "Crimson & Clover," and never knew that a long version existed. Once day I sought it out, listened to it, and sh*t-canned the short version forever!
So I guess it depends. If I listen to an album version from McCartney, and I happen to dig it, then it becomes the Staple.
But I only heard the long version of the aforementioned song, and didn't care for that long, drawn-out organ solo.
