We have more than a feeling that the tribute to Brad Delp is in doubt. Tickets for the Aug. 19 show still aren't on sale, and the promoter, Live Nation, has given no indication when they might be. What's the problem? Word is that the parties involved in planning the show honoring the late lead singer of Boston can't agree on where the money should go. Originally, Live Nation said proceeds from the show at the Bank of America Pavilion would benefit the Brad Delp Foundation, but guitarist Tom Scholz has questioned whether such a foundation actually exists and what its mission is. We're told he's requested more information from Delp's ex-wife, Micki, before signing on the dotted line. During his lifetime, Delp, who committed suicide in March, gave to many of the same causes supported by Scholz, including the Sierra Club and PETA. If the concert does take place, it's still not clear whether the band's original members -- Scholz, Sib Hashian, Barry Goudreau, and Fran Sheehan -- will share the stage or for how many songs. Among those lending their pipes to the proceedings will be Starship's Mickey Thomas, Sammy Hagar, and Stryper's Michael Sweet, who confirms his participation on his website.
