Tiny Tim, the performer known for his vibrating falsetto and his ukelele, and David Cassidy, the Partridge Family heartthrob, were both born on April 12 in different years (Tiny Tim in 1932 and Cassidy in 1950). Tiny Tim died in 1996.

I can’t help comparing their long hair—Tiny Tim with his greasy ’60s locks and David Cassidy with his blow-dried ’70s mane. I wanted hair like Cassidy’s, but the most my mother would allow was a modified Danny Bonaduce.

Here are some pretty groovy performances by each of the birthday boys.

Below, Tiny Tim sings his signature song, “Tip-Toe Thru the Tulips,” on Laugh In. Dick Martin’s reactions are priceless.

Here’s one of my favorite Partridge Family/David Cassidy performances, “Bandala,” from the episode “Soul Club.” The Partridge family has never looked so white, banging their tambourines and swiveling their hips while pseudo Black Panthers accompany them on violins at an inner-city block party/fundraiser. Richard Pryor and Lou Gossett Jr. are in this episode.
