FZ on The Real Frank Zappa Book, p. 116:

The first post-wheelchair appearance [in 1972] was as a reciter, in a performance of Stravinsky's L'Histoire du soldat at the Hollywood Bowl, conducted by Lukas Foss.

Touring versions from Foggy G's We're Only In It For The Touring:

1988
Essentially performed as on MAJNH, an[d] always performed in conjunction with the theme from "The Bartok Piano Concerto #3". In its actual live context, these two songs appear in the middle of "Packard Goose", after the line "Music is the best". There is no "Packard Goose" guitar solo this time round, and upon conclusion of this classical medley, the band returns to the post-solo portion of "Packard Goose".
