My co-worker, who plays ukulele and has a great voice, and I, who play ukulele, would like to perform a song for another co-worker who is retiring in a few weeks. We were thinking of playing "Aloha Oe," but we played that last year for a different retiring co-worker, or IZ's "Somewhere Over The Rainbow," but my co-worker can't find a comfortable key to sing it in and her voice is the whole show. Any suggestions? Hawaiian would be nice, but we mostly just want a "farewell and best wishes" song that would sound good on an ukulele. Mahalo!
