Restored film version of Gershwin performing I Got Rhythm at the opening of the Manhattan Theatre in New York in August 1931 (movie courtesy Edward Jablonski).
In all previously available versions of this rare Gershwin film, the sound pitch changes when the camera angle changes half way through the clip as the two cameras were not running at the same speed. When the two films came to be edited together, the editor inserted a repeat of the last line of the song to help disguise the sudden change of pitch as the 2nd camera angle takes over .
In this version the speed and pitch of both cameras has been corrected and the edited in repeat of the first chorus's last line has been deleted. The version presented here is exactly as Gershwin performed the song at the opening of the Manhattan Theater in New York in 1931.
