Keith Scott, the fine voice actor (and historian of that art form) informs me that the Mickey Mouse's Birthday Party record featured as Today's Video Link was recorded at the Capitol Records Studio on April 8 and 9, 1953 — the latter date being 59 years ago today, as it turns out — and the record was released on August 3 of that year. Keith would know. I suspect the confusion over its release date flows from the fact that it was originally a 78 rpm record but a 45 was released later.
He also informs me that Dave Barry, Dorothy Lloyd and Mexican actor-singer Nestor Amaral were in the cast. I assume Amaral did the singing voice of Jose Carioca but the speaking voice was obviously provided by Stan Freberg. Señor Amaral was a supporting player in one of the two features Disney did with Jose, The Three Caballeros, but he did not do Jose's voice in either. José Oliveira did.
Dave Barry, I should have guessed, did the voice of the goldfish. He was one of the unknown voices in Warner Brothers cartoons…usually the guy who did Bogart when he turned up in something. He did Elmer Fudd in one cartoon (Pre-Hysterical Hare) and actually played Bugs Bunny in one Capitol kids' record. His main line of work was as a very popular stand-up comedian who was featured often on Ed Sullivan's program and all the top variety shows of the fifties and into the sixties. He was very good and probably would have done a lot more cartoons (he told me) if he wasn't out of town so much performing on the road.
But the main thing to note about this whole record is this: If you walked into any record/CD company (whatever they call them these days) and said, "Hi, I'd like to produce an audio story for kids. I'll need a full orchestra, a sound effects man, six or seven singers and maybe ten top voice actors and I'll need most of them for two days," what do you think the odds would be of not getting catapulted to the pavement within seconds? Yet that's how they did these.
