The Parrot-heads must love it.
He's been playing uke for a long time. I saw him playing it outside of Washington DC back in 1990 or 1991.
Check-out this of him playing uke in informal setting.

I would think Jimmy Buffet and a ukulele go together like PB & J.....it just works!! I play a few of his tunes on the uke and he has been seen on stage with Jake S. in the past. I want his Koaloha tho'.
