One of those few TV appearances was, happily, a trimmed down production in 1958 of Cole Porter's Kiss Me Kate, for which Drake recreated his starring role along with his original co-star Patricia Morison. Not much of that TV show remains, though I did post a clip here of him singing his first big solo as Petruchio, "I've Come to Wive It Wealthily in Padua."
Here's another song from that classic TV show. It's the wonderful, and famous duet with Ms. Morison, singing backstage about the mythical mountaintop that looks down on the Jungfrau (a nifty trick -- and joke -- considering that the Jungfrau is the highest point in Switzerland...), the intentionally-hammy, mock-Viennese waltz, "Wunderbar."
I should note that Patricia Morison is still around -- and just four months ago, in March...celebrated her 100th birthday!
