"It's the house that holds all the music," Vince Gill said last Tuesday night (October 5) from the stage of Nashville's Bridgestone Arena. "Everything that came before us and everything that came after us, that's where it will live ... "

The 'house' of which he spoke is the Country Music Hall of Fame and Museum, and Vince was speaking to a sold-out crowd at the second annual 'We're All for the Hall' benefit concert, spearheaded once again by Keith Urban. Last year's inaugural event raised nearly $500,000 for 'the Hall,' making it the most successful fundraiser in the museum's history. This year's star-studded, sold-out show raised nearly $450,000 -- bringing the combined total of both events to roughly $1 million.

"This year's 'We're All for the Hall' benefit, for me, was just over the top," says Keith. "I cannot thank everyone enough for all that they did to make this show the incredible success that it was."

Keith and Vince were joined in performance by some of music's biggest stars at this year's benefit, including John Mayer, Alan Jackson, Dolly Parton, Miranda Lambert, Martina McBride, Charley Pride, Alison Krauss, Emmylou Harris and Billy Currington.

"We are overwhelmed by Keith's generosity, and are so grateful to him, to our board president Vince Gill, and to the amazing line-up of artists and musicians who made the show such a success," said museum director Kyle Young. "The money raised will help us create exhibits, produce programs for school children and the public, and care for our collection."

"The truth is, all the fund raising that's being done tonight -- that's who bought the 13,000 tickets," Vince told the sold-out crowd before performing his set. "They are the ones helping us out."
