Now here's a cause anyone could get behind:  ending hunger amongst the elderly.  And that's just what Carrie Underwood is doing by teaming up with Tony Bennett, Diana Krall, John Mayer and the great Stevie Wonder.

The event that all have signed onto is also a celebration of the iconic singer's 85th birthday. 

The Tony Bennett Live in Concert – Benefit for Drive to End Hunger show is one night only, and takes place at Los Angeles’ Staples Center on September 24, 2011

“It is terrific to be working with AARP once again, especially for a cause like ending hunger among older Americans, which often does not get much attention. I know this event will make a big difference and I am thrilled to be a part of it and have some of my favorite musical performers join me for the concert,” Bennett said in a press release.

The pair has worked together in the past, recording ‘It Had to Be You’ on Bennett’s ‘Duets II’ album, which drops the same week as the concert, on September 20. Additionally, Underwood and Bennett will perform their duet for ‘Blue Bloods’ fans on the show’s season premiere, which airs on September 23.

Tickets for the single-night Tony Bennett Live in Concert – Benefit for Drive to End Hunger event are on sale now through Ticketmaster. To get exclusive behind-the-scenes photos and videos, as well as some free Bennett downloads, visit here.
