AND WAIT, THERE'S MORE: David Lee Roth is busy recording some new material with his new band in a New York studio. But they don't miss him out on the hustings with the new Sammy Hagar-led Van Halen. In fact, at one of the band's first shows, in Little Rock, Ark., fans held up a huge banner featuring a picture of Roth with a big line across his face. The slogan read: "No More Daves." . . . Neil Sedaka is putting together a benefit album dedicated to Howard Greenfield, his longtime songwriting partner who died recently of AIDS (they wrote such hits as "Breaking Up Is Hard to Do" and "Happy Birthday Sweet 16"). Called "Me and My Friend," the record will feature Sedaka performances of his favorite Greenfield lyrics with all profits going to AIDS research. . . . If you're a blues fan, there's a new hot line to call for the latest information on upcoming blues shows, festivals and radio programs. Just phone: (213) 469-9597. . . . Heavy-metaler Y&T have left A&M for Geffen Records. . . . Ex-Bow Wow Wow vocalist Annabella L'Win comes back this summer with a solo album on RCA called "Fever." . . . And our condolences to the family of Linda Creed, who died recently after a lengthy battle with cancer. With partner Thom Bell, Creed had written many hits for the Stylistics and the Spinners as well as "The Greatest Love of All," recorded recently by Whitney Houston.
