I came across this on YouTube and didn’t know what to expect.  What I quickly realized is that both Cher (despite her idiot politics) and Dolly are amazingly talented and exceptional performers and the Tubes were vastly underrated.  This was most likely from Cher’s show in the mid-seventies, but I can’t say for sure.  Strictly a guess.  But I can tell you this.  It’s my video of the day.  Enjoy.
