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

Hi all. This is a very odd pergunta but one I hope you 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 mesa, tabela in the schoolyard on his own just behind Olivia Newton John 2 minutos and 24 segundos into the song. He looks quite lonely, like he really needs a hug. I am composição literária an artigo on unrecognised extras in famous filmes and would dearly like to get in touch with him. If anybody knows this actor's name or can help I'd really appreciate it. Thank you for all your help!
