Here's a video that is a few years old that I just came across. Usually when I find these gems, I've fallen down that dangerous YouTube Vortex where I just the keep clicking and clicking and clicking. This time, I found a clip of the performance on Tik Tok and I had to find the full performance.
This is from a Billy Joel concert at Citizens Bank in Philadelphia. Billy HAD to bring up some Philly guys...BOYZ II MEN! Who better to harmonize on For The Longest Time...just so cool.
Check it out, it's worth the five minutes...just careful not to fall into the YouTube Vortex!
