Ah, Sesame Street. Right up there with Mr. Rogers there is nothing like this great show. Here are a few favorites I found on YouTube.
Bert and Ernie Go fishing… This is a classic.
C is for Cookie
Yip yip aliens meet the radio.
Johnny Cash and Biff Sing Five Feet High
Misc Celebrities Sing the Alphabet Song (Including Capt Picard in Civies…)
Rubber Ducky Song
Minorities weren’t quite as fast to grab a pitch fork when this was broadcast…
