BOSTON -- Organizers of the third annual Hot Stove, Cool Music: The Fenway Sessions are hoping the hot summer sun shining on them in the right-field roof deck on Tuesday afternoon is a sign of things to come.

Last year, organizers had to scramble as torrential rains forced planners to quickly break down the stage and move it underneath the right-field bleachers.

This year, Hot Stove, Cool Music: The Fenway Sessions, presented by Iron Mountain, is planned for Aug. 24 in front of the Red Sox bullpen in right field with seats in the right-field grandstands.

Tickets are $40 each and go on sale on Wednesday at noon ET, and are available by going to www.redsox.com. Proceeds will benefit The Foundation To Be Named Later, the official charity of Red Sox general manager Theo Epstein and his twin brother, Paul.

The current lineup includes John Legend, Buffalo Tom and Kay Hanley. Also taking part are French Lick, featuring Boston Celtics managing partner & co-owner Wyc Grousbeck, and the Hot Stove All-Stars, featuring Epstein and Gammons. The event will be emceed by comedian and television star Mike O'Malley.

"This is the third time we've had the outdoor Fenway Park version of Hot Stove, Cool Music, and it's been a great success so far," Epstein said. "We've raised over $600,000 for The Foundation To Be Named Later."

"Iron Mountain is very proud to be associated with this event and in helping the Foundation to Be Named Later," added Shaun Kelley, vice president of New England for Iron Mountain. "This is a great charity focused on the youth in our community. As a corporate citizen headquartered in Boston, we are honored to support this worthy cause."

Seven children from "The West End House" and "Bell," two of the eight Boston-based community agencies that benefit from the Epsteins' foundation, were on hand for Tuesday's announcement at Fenway.

"We feel so fortunate to have the support of the Foundation to be Named Later," said Earl Martin Phalen, Bell co-founder and CEO. "Since we partnered with them three years ago, we went from educating 3,000 young scholars to educating 11,000 elementary school children. During this period, we've seen amazing gains for our children."

Baseball Hall of Fame writer and guitarist Peter Gammons returns this year after missing last year's event with a life-threatening brain aneurysm.

"Last year's event, besides being remembered for the [bad] weather we had, was also noteworthy for the absence of [Gammons]," Epstein said. "We're ecstatic that he's back. It didn't seem like a real Hot Stove, Cool Music event without him. This year's Fenway concert will mark his musical return to Fenway Park."

"Some people have golf tournaments, we decided to have rock n' roll concerts to raise money," said Gammons, sporting a bright yellow Hawaiian shirt. "It has evolved. The idea is that we can have a lot of fun, come to an event and they can benefit some people who normally do not get benefit from these kind of events."
