Harry Steinberg, Class of '31, is the artist du jour for the Beatles on Ukulele project.
The concept of the site is to have every Beatles song covered, and on each one, in some way, the cover band has to use a ukulele. The songs are all free and downloadable; the effort is mostly about getting some attention for the contributing bands. Each Beatles song gets a write-up with discussion and backstory (e.g. The Ballad of John and Yoko is described as a 2-minute tweet).
Steinberg, who sings a retitled When I'm Sixty-Four, turned 100 this month. He is a veteran of World War II, stayed in the army into his 50s, then started a career as an ENT doctor. He's also a found object artist, and lives in L.A. with his wife Claire.
For the record, the song's original author, Paul McCartney, is now 68.
