John Wayne Gacy: REO Speedwagon

Gacy - who was dubbed The Killer Clown because of his public performances as a children's entertainer before his crimes were discovered - killed at least 33 men and young boys in Illinois during the 1970s.

In an interview before his execution in 1994, Gacy stated that he was fan of rockers REO Speedwagon who had hits with Keep On Loving You and Can't Fight This Feeling.
