Host Dick Clark

Dick Clark made his debut as permanent host of "Bandstand" on Philadelphia TV 
station WFIL when original host Bob Horn was arrested for driving while intoxicated
and was subsequently fired by the station. Clark had been a disc jockey on WFIL
radio and had substituted for Horn when he went on vacation. The name of the 
show was changed to "American Bandstand" in August of 1957 when it went
national to ABC-TV.
