A rare mimed musical performanve recently appeared on YouTube, of Mike McGear with the song "Leave It" from 1974. This was released as a single in conjunction with the album "McGear", where Mike was backed by his brother's group, Wings.
This performance took place on the Spanish TV channel RTVE in their program series "Señoras Y Señores" which was broadcast on February 15, 1975. RTVE uploads a new episode of this programme every Sunday on their web portal, which is the source our uploader has downloaded this clip from. The song is a Paul & Linda McCartney composition.
Mike also performed "Simply Love You" on the same show. You can watch the entire episode here. It includes The Rubettes among others, the others being mainly Spanish artists.
