Yes.

Berkhamsted Ukulele Random Players are at Bartin-le-Clay tonight: see separate thread for details http://www.mudcat.org/thread.cfm?threadid=119365.

And there's a short video of a recent gig on YouTube

As for recorders: they're serious, too. I love it that both of my daughters who play oboe and French horn to a high standard both still play and gig with recorders.

And don;t confuse "serious" with "no fun". Many things can be both.
