It's assumed that the video bootleg labelled Spectrum Theater on 17th is actually this date and as such setlist details have been copied from there.
Setlist.fmMorning Call (George Smith) 14 Sep 1990: "Faith No More -- which opens for Billy Idol at the Spectrum in Philadelphia tomorrow [...] So far, Faith No More has only done two dates opening for Billy Idol."
"Morning Call" Allentown, PA, 22 Sep 1990 (Cheryl Wenner) - "The headliner's share of last weekend's sold-out concert at the Spectrum was, sad to say, undermined by theatrics and cartoonish posturing, but San Francisco's Faith No More, whose second album "The Real Thing" is already a best-seller, no doubt won new fans with its 45 minute set."
