A cat upstages a group of musicians with a surprise guest appearance on stage that leaves the audience and the performers laughing.

How or why the cat ended up in the building or on stage is anyone's guess. But, at times it appears he's looking for the best seat in the house.

The cat reminds me of people who show up at a concert late and then interrupt the show when they can't find their seats.

Make sure you watch this all the way to the end. There's a surprise that will make this special guest appearance even more humorous.
