I don’t know who the two cute girls in the back are, but the African American boy at the keyboard was the right wing on my soccer team. And you may not recognize her, but the pigtails in the foreground belong to Kimya Dawson. She did several of the songs on the soundtrack for Juno and is a brilliant folksinger. Yes, I used to have blonde hair in 1982 and those pearly whites looked much cleaner before I knocked them all out doing a wheelie on a dirt bike two years later.
Brilliant!
