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

Hi all. This is a very odd 質問 but one I hope あなた 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 表, テーブル in the schoolyard on his own just behind Olivia Newton John 2 分 and 24 秒 into the song. He looks quite lonely, like he really needs a hug. I am 書く an 記事 on unrecognised extras in famous 映画 and would dearly like to get in touch with him. If anybody knows this actor's name または can help I'd really appreciate it. Thank あなた for all your help!
