I got the teal album when it came out in 1972, after I saw Wakefield interviewed on David Frost's show, and I still play it a few times a year. His back-up band on that album included Tony Trischka on banjo, Russ Barenberg and Peter Wernick (!) on guitar, and Kenny Kosek on fiddle. As you can hear in Allen's link, the "Jesus Loves His Mandolin Player" instrumentals were pretty out there for the time. Forgive the heresy here, but my favorite piece on the album is "Hallelujah on the Fives," which Wakefield wrote as a banjo tune.
Old Dog Dave, since you say that bossa nova is one of your guilty pleasures, you might take a peek down the choro rabbit hole.
