(The description says it's the show's 35th anniversary. It's not -- the musical opened in 1966.)
Here are two songs. The joyous and very funny "Bosom Buddies," sung with Anne Francine, and then "That's How Young I Feel" -- probably my least-favorite song in the show, but it's an energetic dance number which Lansbury throws herself into.
The song quality isn't great, so you'll like miss some of the lyrics, and the video is shot somewhat at a distance and a bit washed out, but overall it's very watchable, and as a part of a Broadway history it's a nine-minute valuable joy.
