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

Hi all. This is a very odd 问题 but one I hope 你 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 youtobe clip of the song. The extra, who is a man, appears sitting on a 表 in the schoolyard on his own just behind Olivia Newton John 2 分钟 and 24 秒 into the song. He looks quite lonely, like he really needs a hug. I am 写作 an 文章 on unrecognised extras in famous 电影院 and would dearly like to get in touch with him. If anybody knows this actor's name 或者 can help I'd really appreciate it. Thank 你 for all your help!
