I found video with a Jimmy Durante/ Bing Crosby duet. It’s called “Chidabee, Chidabee, Chidabee (Yah! Yah! Yah!)” I can’t say for sure but I’d guess this is from Bing’s 1950’s radio show.
When I eventually get my Barbara Walters style interview with Q, we’ll of course discuss what type of tree he’d like to be and dredge up repressed childhood memories which make him cry.
