Different Musicians Coming Together, A Little Earlier

A few changes have been announced for Sunday night’s tribute to late Boston vocalist Brad Delp at the Bank of America Pavilion.

Sammy Hagar, Orion the Hunter and former Jefferson Starship singer Mickey Thomas are out and hometown rockers Extreme are in.

The Hub band will join the already announced line-up of Michael Sweet of Stryper, Godsmack, RTZ, Farrenheit, Ernie and the Automatics and Beatlejuice- Delp’s Beatles tribute act.

Current and former members of Boston will also take the stage for the show, entitled “Come Together” in honor of Delp’s abiding love for the Fab Four.

A new earlier start time of 5:45 was also announced.

The majority of proceeds raised from “Come Together” will go to The Brad Delp Foundation created by his children, family and friends. Tickets are $35 and are available at Ticketmaster and 617-931-2000.
