With or Without You, being sung during Super Sproul by the incomparable 2000 Octet. The guys are (L to R) Steve Chu (bass), Ryan Antonelli (bari), Matt Johnson (tenor), David Martinez (tenor), Kevin Lam (tenor), and Ben Park (bari). The soloist is Phil Dwelle.
I was just listening to the 2001 Octet singing the same song on Octopella, so I was so pleased to be able to compare to two. :)
I hope that more Octet videos surface!
