John, you're on the mark. TAKRL, TMQ & the Swingin' Pig did some very juicy live albums. Tanks for the Mammaries may have been TAKRL's greatest moment. A 2 LP compilation with each track by a different artist. Beatles, Hendrix, Simon & Garfunkel, Cat Stevens, Bowie, Rutles, Zappa, Jethro Tull, CSN&Y, Spirit, The Band, Fleetwood Mac, Steely Dan, Springsteen, and more, ending with Groucho Marx! I'm sure you can envision the cover! Those really were the days!
