App,
KJY's first song for MGR was "Thangathoniyile" in USV but technically speaking KJY had sung in a MGR movie way back in 1966. The movie was Parakkum Paavai in which he sang சுகம் எதிலே இதயத்திலா along with TMS and LRE [a very rare combo song] and his playback was for Chandrababu [again a rare occasion].
Regards
