When did Gord last perform "Your Love's Return"?

[Dave, Melbourne,Australia]

I took a liking to this overlooked gem after seeing the video of Gord's 1972 BBC concert:

The song starts 24 minutes into the first link.
Does anyone know roughly when he last performed it in concert? And why he hasn't performed it in recent decades?
(I could ask the same about "Saturday Clothes", "Affair On Eighth Avenue" and other songs in this concert.)

The BBC Concert is a great glimpse into a what was a very intimate Lightfoot performance.
The last time he did some of these songs? I don't know when, but I agree that it's a wonderful song. I know there has been vocal range change over the years perhaps that has something to do with it or just the time limits in each concert. I know at each concert I've gone to I wished some songs could have been included. There are so many gems, and he can't do every song although we wish he would. We wouldn't mind if the concert length was increased to five or six hours.
