The Santa Monica Observer has an item about the discovery of a "lost" Bob Hope recording - Click on the link to see the complete report, but this is a quote of the main bit - 

"One day in 1984, an 81 year old immigrant turned entertainer, walked into to a Hollywood recording studio. Bob Hope came to Sunwest Recording Studio to sing a comedic number about another entertainer, an old friend of his named Bing Crosby. It lasts for three minutes and is entitled, Of Bing I Sing.The song was intended to be incorporated into a television broadcast of the Pebble Beach Masters Golf Tournament of 1984. Perhaps it was, perhaps it wasn't; but either way, the song was lost for thirty two years. Until it turned up in a Santa Monica Alley, to be discovered by a certain local newspaper publisher.This town is filled with lost video and audio, and it's a shame because it's so much a part of LA history. James Hardy of Bob Hope Legacy, LLC (www.bobhope.com) says that he hasn't heard the tape before. Mark Brodka, spokesman for the Crosby family, confirms they don't have a copy of "Of Bing We Sing" either."
