Although Jason Marsden is a talented singer, he did not perform the musical numbers in the film. It was out of Disney's concern that a Broadway-style musical actor should provide Max's singing voice instead. That actor was Aaron Lohr, a personal close friend of Jason's. However, two decades later, at the 2015 D23 Expo, during a panel celebrating the film's 20th anniversary, this was rectified when Jason Marsden and Bill Farmer sang a duet of "On the Open Road" together without any prior rehearsing.
The movie didn't do well at the box office, but did very well in video sales and rentals.
