Very sad...had no idea he was even sick! Never got to meet Charlie-O, but remember him well from when "Wheel" came to Dallas the first time, back in March 2001. Aside from the great pipes, he was an ace at warming up an audience...perhaps one of the best ever.
Speaking of "Wheel" and Dallas connections, the first hostess of the show (1975-82) was actress and gossip writer Susan Stafford, who just happened to be the second wife of Gordon McLendon!
