Disney Sing-Along Songs is a series of videos on VHS, betamaxs, laserdiscs and DVDs with musical moments from various Disney films, TV shows and attractions. Lyrics for the songs are displayed on-screen with the Mickey Mouse icon as a "bouncing ball". Early releases open with a theme song introduction (written by Patrick DeRemer) containing footage featuring Professor Owl and his class, seen originally in 1953 in two Disney shorts, Melody and Toot, Whistle, Plunk, and Boom (voiced then by Bill Thompson). Professor Owl (now voiced by Corey Burton) hosts some of the videos, while either Ludwig Von Drake or Jiminy Cricket host others, and later volumes, as well as the two Christmas videos, did not have a host at all. The footage of Von Drake and Jiminy Cricket were taken from several television programs (including the Walt Disney anthology television series, and Mickey Mouse Club) featuring the characters in the 1950s and 1960s.
