American Bandstand, abbreviated AB, is an American music-performance and dance television program that aired in various versions from 1952 to 1989, and was hosted from 1956 until its final season by Dick Clark, who also served as the program's producer. It featured teenagers dancing to Top 40 music introduced by Clark; at least one popular musical act—over the decades, running the gamut from Jerry Lee Lewis to Run–D.M.C.—usually appeared in person to lip-sync one of their latest singles. Freddy Cannon holds the record for most appearances, at 110.
