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

Hi all. This is a very odd pregunta but one I hope tu 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, tabla 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 escritura an articulo on unrecognised extras in famous cine and would dearly like to get in touch with him. If anybody knows this actor's name o can help I'd really appreciate it. Thank tu for all your help!
