I was honored to see Slim perform live, ca. 1985, in a baby blue western-cut suit. Man, was it ever clean.

His version of “Rose Marie,” the title song from the venerable operetta that spawned “Indian Love Call,” became a huge hit in England in 1955, staying at No. 1 on the charts for 11 weeks.
Whitman’s other hits included “Have I Told You Lately That I Love You,” “Red River Valley,” “Danny Boy” and “I’ll Take You Home Again, Kathleen.” …
Whitman told the AP in 1991 that he wanted to be remembered as “a nice guy.”
“I don’t think you’ve ever heard anything bad about me, and I’d like to keep it that way. I’d like my son (Bryon) to remember me as a good dad. I’d like the people to remember me as having a good voice and a clean suit.”

I just knew that you’d have something to say about that late, great Slim. He’ll be missed by everyone who ever watched late night television in the late 1970s and early 80s. Una Paloma Blanca has gone off to see his own Rose Marie!

You were the first person I thought of when I heard the news 😦
Then I thought of Martians:
