I would love to see it, but have no idea how long he's on for
Yehaa Bob is on from 8PM till midnight. His schedule varies a little bit depending on what else he has going on but for the most part, he plays Wednesday through Saturday nights. You can come and go from the show as you'd like. It's not like it's a theater type setting.
His website is here.
His Facebook page is here.
There's various videos on YouTube about his show. Just search for "Yehaa Bob". Here's one of them:
It really is a lot of fun. He's remarkably talented and gets everyone involved in some way or another. If for nothing else than to ask you where you're from.
I think you'd really enjoy it.
