Are there any Ukulele Bands that don't feature vocals?

I enjoy listening to a lot of bands who don't use any vocals such as the david grisman quintet (for anyone who might enjoy the mandolin as well). I was wondering if there were any ukulele bands like that. I've had no luck finding any so far. If there are any who's music sounds similar to The Night Owls or Beirut that would be awesome! Thanks.

I haven't listened to a lot of their stuff, but the Ukulele Orchestra of Great Britain seems "intrumentals" heavy.
