JF: My next-door neighbor at the time was a guy named Paul Fox, who produced R.E.M., 10,000 Maniacs, Jakob Dylan, Björk, and Phish. And the guys from Phish were huge Trekkers, and they used to come to his house to rehearse. Actually, I think they may have rehearsed in my guest house! This was up in Lookout Mountain, in L.A. But they got wind that I played trombone, and they didn’t know I wasn’t that good, but they asked me to the studio, so I came out to the studio to play trombone on Hoist. I played some music; I didn’t do it so well, but all of the outtakes from my trombone playing became a song called “Riker’s Mailbox,” because at the time, my mailbox vaguely looked like a cow, with black and white spots, only this one had been beaten up many times by cars running into it and people running by and smacking it. So my outtakes were named after the mutilated cow mailbox that was the identification of the front of our house, the Hoist album went platinum, and, as a result, I am the proud keeper of a platinum record. So there you go.

It is the best kind of true: technically.

That was a rollercoaster my dude. Loved it, congrats on the platinum record, heh.

Huh, didn't realize Jeffrey Combs wasn't on TNG.
