"Many Too Many" is a song performed by Genesis and released as a single from the album ...And Then There Were Three... in 1978. The single peaked at number 43 on the UK Chart. Its B-side had two non-album songs, "Vancouver" and "The Day the Light Went Out", both of which were released on compact disc on the Genesis Archive 2: 1976–1992 box set. A music video was filmed for the song.
The song includes the last use of a Mellotron on any Genesis studio recording, though Tony Banks did use one (albeit very sparingly) on his solo album A Curious Feeling, released in 1979.
