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

Hi all. This is a very odd soalan but one I hope anda 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 YouTube clip of the song. The extra, who is a man, appears sitting on a meja, jadual in the schoolyard on his own just behind Olivia Newton John 2 minit and 24 saat into the song. He looks quite lonely, like he really needs a hug. I am Penulisan an artikel on unrecognised extras in famous Filem and would dearly like to get in touch with him. If anybody knows this actor's name atau can help I'd really appreciate it. Thank anda for all your help!
