I'd have to take issue in a small way here. To say Burl Ives wasn't too bad as an actor is a little unfair. Burl had some klinkers (Brass Bottle, Ensign Pulver) but he had some great roles as well, mnostly on stage but Wind in the Everglades (title may be wrong slightly) and Cat on a hot tin Roof come to mind. He was in a bunch of TV plays in the early 60's. I put him in the same class as Will Geer.

Johnny Cash is a very good actor ( The Pride of Jessie Hallam, and a cop film he did with Andy Griffith as a bad guy. come to mind)

Edward Woodward was a singer for quite awhile with good success. The Equalizer wasn't terrible but Breaker Morant and The Wickerman are masterpieces.

However, much as i liked Roy Orbison....
