"Can You Feel the Love Tonight?" was the FIRST song Tim Rice and Elton John completed for the 1992 "Lion King."
It was also originally supposed to be sung only by Timon and Pumbaa. According to Ernie Sabella, who voiced Pumbaa, Elton was NOT happy that they were using the ballad as a parody, so it was reworked.
Other fun fact, there were no lions used in the film it was all done by voice actor Frank Welker, who created them by growling into a metal garbage can.
