Was at a friends (singer/songwriter) house when this came on the tele. She knew it was gonna be on and had her tv programmed to start it. Since we do a version of some of the songs, we played along with them. It was a blast playing along to a live concert with some of the legends singing for you.

It was actually really entertaining.
Sorry if this is a bit cryptic, but I'm feeling a bit brain-dead today.
