There's also The Fastest Guitar Alive (1967), which predates the "Sabata" films and features the legendary Roy Orbison as the guy who can pick a tune and shoot at Indians with the same instrument. Script is said to have been offered to Elvis, who took a pass, though it's still better than most of Elvis' late 60s pictures. The songs given to Orbison are, sadly, on a par with "Do the Clam."
