A 1992 re-release of the single managed to reach the Top 40 in Germany.
Former Genesis member Steve Hackett in interviews said "Mama" was his favorite song from the band after his departure, calling it "beautifully haunting."
There are at least four versions of the studio recording of "Mama".
The song was covered by the French extreme metal band Carnival in Coal and released on their album French Cancan (1999).
"Mama" was covered by the Finnish heavy metal band Tarot as the second track on the single for "Undead Son".
