So the movie Juno has practically been on loop on HBO this month, so despite having seen it several times I've watched all or part of it many times again. I've been paying more attention to the music selections and the smaller details recently.
This particular song, "All The Young Dudes" by Mott The Hoople plays during what starts off as a fairly innocent scene towards the end and turns into an emotional turning point in the film.
I remember thinking when I first heard it that it sounded like a David Bowie song. Well, it turns out that's because Bowie wrote the tune for the band in an effort to keep them together. He was a big fan apparently and originally offered them his song "Sufragette City" from his then unreleased Ziggy Stardust album.
On this performance, Bowie accompanies the band live at the 1992 concert honoring Queen frontman Freddie Mercury.
