I wouldn’t say that anyone in this ad necessarily went on to attain the predicted ubiquity, but the piece does feature some amazing players who’ve had long careers. There are even two future ex-Poison guitarists in Richie Kotzen and Blues Saraceno. Here’s the complete listing:
Danny Gill of Hurricane Alice (before they became “Hericane” Alice)
Johnny Feikert (listed just as “Johnny F.”), Brad Lang (now playing bass for Y&T) & Willie Hines of Jet Red
Donny Roberts of Webb Wilder & the Beatnecks
Every one of these guitarists appears to still be active.
