Actually, it gets even better than that: He recorded Will Ferrell's jazz flute solo in Anchorman. (The scene is below.)
Born outside of Montreal, Buckingham had hippie parents -- "My mom saw [my name] in a dream," he says. They were also songwriters and folk musicians, and after the family moved to L.A. Buckingham attended art school in South Central where he studied jazz band and acting.
Buckingham did TV commercials, plays, and, of course, the Who's the Boss part.
"I was only like 13 when I started acting professionally in theater. In Variety and Hollywood Reporter, I was getting the best reviews of anyone in the play," says Buckingham, immodestly.
He eventually decided to focus on music and, at age 20, he was approached to record saxophone and flute on Dr. Dre's The Chronic. (The, um, best rap album of all time. No big deal.)
He took the gig not really knowing who Dre was. "I went to the studio," he remembers. "Snoop was there. We were just playing pool. I didn't know who he was either."
