Yep. Dino did a cool version of this too. Back in that late 60s period when he was doing a lot of country covers, like "Houston", "King of the Road", "Welcome To My World" and "My Shoes Keep Walkin' Back To You". I still think DM could sing circles around Sinatra.

I've never heard the Robert Mitchum version but would like to. I always thought he was a pretty good singer too. (Even though he DID NOT sing the theme song to "River of No Return" like a lot of people think--they even claimed that on an A&E Biography of Robert Mitchum. That was Tennesee Ernie Ford).

(p.s. Mitchum was even cooler than Dean Martin, IMO)
