...Sources claim WTKK - which just lost the I-Man [Don Imus] as its 96.9 FM Talk morning host - has turned up its pursuit of Deno and Gerry which, we’re told, started waaaay before the Rutgers lady hoopsters got to the Big Dance!...[T]ime is of the essence for ’TKK, which needs a new morning show - like “Dennis & Callahan” which is No. 1 with men 24-54 - that will immediately generate numbers as well as cash by the start of the all-important fall ratings book."Getting ‘Dennis & Callahan’ would be a boon for ’TKK - or WBCN [website] or whomever - since the station would have to pay big for them, but they’d be guaranteed ratings and sponsors right off the bat," said a spy. "And imagine the free publicity."So why would you bring in an unknown and have to spend $1 million promoting him? It doesn’t make sense,” said Deep Dial.
