Burton Cummings - You Saved My Soul

I'm pretty sure the commercial 45 is the same as the short side of the
DJ 45. Also, I believe it is an edit of the LP version.

Dale, the US commercial 45 is an edit of the LP version. The Canadian 45 is the full LP version.

I, too, did an edit to match the US 45 years ago, and don't recall the exact points. But on the album version, there's a double first verse. On the single, it's half as long, and there's a very tricky spot used to get the edit to sound smooth like the 45. If I recall, it was after the line "oh baby it was so wrong" and then going to the line "something in the bottom of my heart". I remember attempting this once, where the EQ on his voice suddenly changed - sounding very much like a forced edit (which is not how the 45 sounds), and then getting the edit right on 2nd attempt.

Also, there's also an edit in the bridge in a very weird place - in the middle of a sentence, such that a new sentence is the outcome. In the single version, it goes, "you picked me up at the bottom, love". On the original, it goes "you picked me up at the bottom" (without the word "love") into a whole new line - "You saved my soul, save me honey, go and save me in the morning, love". And they cut right before the word "love" to get the 45 version.

There very well may be more than these 2 edits but those 2 were the trickiest, so they stand out clearly.

And besides the longer US LP version (=Canadian 45 version), there's also like a 7 minute version in a film called "Melanie."
