When the attraction closed in 1988, most of its audio-animatronic characters were moved to Splash Mountain, while two of the long-necked geese were transformed into the G2 droids in the queue area of Star Tours and the rock and roll stork is now used to train new animatronic programmers.
The building was used as office space until Innoventions opened in 1998.

- Unlike Carousel of Progress which rotated clockwise, America Sings rotated counter-clockwise. Also unlike its predecessor, America Sings only used the lower level. The lower level would again rotate clockwise as part of Innoventions, the successor to America Sings.
- According to an interview with Alice Davis, Chill Wills who did the voice of Saddlesore Swanson, stated that he wouldn't go inside the carousel theater, because he believed he would be strangely killed, which lead him to leave the cast before the ride was opened in 1974.
- Who shot the hole in my sombrero? was originally made with a Mexican accent, but the press didn't like it and ordered a change for the accent. It was later made with a Texan accent. However, the Mexican accent version still exists on the 1974 LP recording of the attraction.
- This was the first attraction created without Walt Disney.
- The animatronics were designed by Marc Davis.
On July 8, 1974, nine days after the attraction opened, 18 year old Disneyland cast member Deborah Gail Stone was accidentally crushed to death between the building's rotating wall and a stationary wall. She either fell, stepped backwards or tried to jump from one stage to the other as the rotating wall began to move (it moved every 2 to 4 minutes which was how long each act was). A guest in the adjacent theater heard her screams and notified the ride operators. By the time the guest and ride operators got to Debbie it was too late. She died from her injuries. Deborah Gail Stone was pronounced dead at 11:00 PM. She'd recently graduated from Santa Ana High School. Debbie got a job at Disneyland to earn money for college. Minutes before her death she'd called her parents to ask for their permission to get engaged as she'd fallen in love. Deborah Gail Stone is buried in Fairhaven Memorial Park in Santa Ana, Orange County, California.
