"Heavy Duty Judy" started as a simple two-bar riff Frank Zappa used in 1979-1980 as a showcase for a guitar solo, occasionally using it as a curtain raiser also. It appeared in this form on the 1981 LP Shut Up 'n Play Yer Guitar -- just a solo with a repetitive riff to back it up. For the 1984 tour, Zappa developed the riff into a piece, with a melody and a verse-and-chorus structure. It was performed occasionally during that tour and with better results in 1988 when it was once again used as a curtain raiser (it opens disc one of The Best Band You Never Heard in Your Life). The latter arrangement prominently featured the brass section and had become, in every aspect, a full-blown instrumental piece. The tribute band the Muffin Men even included it in its repertoire. "Heavy Duty Judy" is one of only two or three pieces from the triple-guitar set that survived as a regularly performed piece of music.
