Morning 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."
