Shos noted in the AFI thread that Sophia Loren's and Peter O'Toole's singing in Man of La Mancha was atrocious.
I recall Lee Marvin singing "I Was Born Under A Wandering Star" in Paint Your Wagon. It was pretty bad. The key seemed to change every note.
Kirk Douglas sang "A Whale of A Tale" in 20,000 Leagues Under The Sea and it was halfway decent.
Frank Sinatra acted in several movies and was generally decent. I don't remember Elvis Presley ever acting like anything except a bad actor.
What's your take on these crossover atrists?
