Can anyone identify the extra who appears behind Olivia Newton John 2mins24secs into the song "Summer Nights"?

Hi all. This is a very odd প্রশ্ন but one I hope আপনি can help me with. I am trying to track down one of the actors who appeared in Grease. He is an extra who had no lines but appears sitting on his own in the background during the song "Summer Nights" I have included a link to a ইউটিউব clip of the song. The extra, who is a man, appears sitting on a টেবিল in the schoolyard on his own just behind Olivia Newton John 2 মিনিট and 24 সেকেন্ড into the song. He looks quite lonely, like he really needs a hug. I am লেখা an প্রবন্ধ on unrecognised extras in famous চলচ্চিত্র and would dearly like to get in touch with him. If anybody knows this actor's name অথবা can help I'd really appreciate it. Thank আপনি for all your help!
