In the Absolutely Fabulous episode "The Last Shout (1996), the main character, Edina Monsoon, imagines this song being sung by dancing hippies.
In the movie Connie and Carla, when the bar reopens as a dinner theater, Connie (Nia Vardalos) says the guys should enter from the back of the house on "Good Morning, Starshine". They enter, singing the opening verse of the song. (This does not appear in the soundtrack of the film that was released, however.)
