Here's a different side of McCartney:
Here's a recent live version:
Here's the other song that was new to me.
Paul did comment on TLC's 1995 similar themed "Waterfalls":
"McCartney himself called out TLC in a 2007 interview with the A.V. Club:
AVC: Are there any songs of yours that you think deserved to be bigger than they were?
PM: There's quite a few, actually. I like…. There's one called "Daytime Nighttime Suffering," which I think's really cool. One called "Waterfalls," I think is nice. In fact, somebody had a hit, a few years ago, using the first line, "Don't go jumping waterfalls/ Please stick to the lake…." And then they go off into another song. It's like, "Excuse me?"
AVC: TLC ripped off Paul McCartney? I had no idea!
PM: I think so."
Were you familiar with either of these songs? Like them?
