I just uploaded a song entitled "Wait'll You See My Gal". May Singhi Breen played the uke and Arthur Fields on vocals. I believe this was recorded in 1920's. It seems the sound of Breen's uke is so different from the sound of today's ukuleles. is it because she used "real gut" strings? could this be the authentic ukulele sound?
