pop singer

[tiny tim]

What is the surname of pop singer, who shares his initials with a once famous film production company?

[littleoldme]

Educated guess here, as it's a ONCE famous company, not a currently famous one. Could it be Roy Orbison, who may have the same initials as the long-defunct RKO? (I have no idea as to Roy Orbison's middle name).

Roy Orbison's middle name was Kelton so I am guessing that you had it right with RKO.
