RADIO DAYS: When KLOS-FM morning madmen Mark & Brian invited Barry White, the man with the most awesome basso profundo in show business, to do their show Tuesday, we knew something wild was bound to happen--especially since the radio bad boys had been playing snippets of White’s hits on the show for weeks (White also has a new album coming out called “The Man Is Back”). But people have joked about White’s rumbling baritone for years--what new twist could we expect from the impish deejays? Easy. They got White to go along with a goofy chemistry experiment--they fed him a tankful of helium. Sounding like a cross between Flip Wilson and Prince, White playfully recited ‘70s-era lyrics (“Take off your brassiere, my dear . . .”), saying with awe: “You guys are crazy .” Thanks to stunts like this, Mark & Brian have catapulted to the No. 2 position in the morning ratings, leaping past Power 106’s Jay Thomas and trailing only KIIS-FM’s resurgent Rick Dees.
