Well, Octet fans, I've found it. An Octet member singing something not-a cappella.

It seems that at one time Jordan was a member of a  folk/folk rock/bluegrass trio called Le Soup du Jour (translates into something like 'soup of the day'.)

Anyway, all the songs are great, but Jordan has the lead in a snappy li'l number called Ramona. He also plays the guitar in all four songs. He's multi-talented! The Myspace Page looks a bit deserted - no check ins for over a year. It's too bad, because they're a talented group.

Dianna was in the Octet opening video in 2003. She played the Almost Famous-y reporter who followed the Octet. FUN! I don't know who the other woman is. They have a great sound. Excellent harmonies!
The picture they used for the video is almost Octet-ian, except there are only six guys instead of 7. (Or eight, as some Octet's are prone to having.) I realized, as I was listening to George Baker's "Little Green Bag" on my mp3 player, that I was auto-arranging it in my mind, a cappella style. Actually, I can't write music at all, but I could hear how the song would be sung a cappella. Except for the barritone part. I don't understand barritone.
