Pretty sure that the NYE show was the first time, and I don't recall it since. Here an excerpt from my post on that show:


Highlights Tonight, encore

Feeling Alright: Total off the cuff, a Capella version of Dave Mason’s gem (famously covered by Joe Cocker) that seamlessly morphed into Bill Withers gem, Grandma’s Hands. I know a lot of you may have limited experience with Bill Withers, but he has had a #1 “Lean on Me”, 2 #2’s “Use Me” &amp; “Just the Two of Us” and a #3 “Ain’t No Sunshine”. After the show I asked Grace about this, and she said she just “felt” the Dave Mason song and then when she got to the chorus  that says “I ain’t feeling so good myself” she realized that was NOT how she was feeling and better bail fast.   http://www.youtube.com/watch?v=qv5pagal-ls
