Stars including Beau Bridges, John Stamos and Andrew Rannells performed classic Broadway hits in support of the fight against Alzheimer's disease.

Celebrities brought a little bit of Broadway to Los Angeles on Wednesday night at the 22nd annual "A Night at Sardi’s" gala at the Beverly Hilton hotel. Hosted by Mad Men’s Ben Feldman and Suit’s Sarah Rafferty, the fundraiser benefited the Alzheimer’s Association.

The cast of The Big Bang Theory (Mayim Bialik, Johnny Galecki, Simon Helberg, Kunal Nayyar, Jim Parsons, Melissa Rauch and Kaley Cucoco-Sweeting) have been through their share of costumes performing musical numbers for five years. This year the group, also known on the stage as "The Bangers" took a break from performing to receive the Abe Burrows Entertainment Award from Bob Newhart.

"We thank them for coming here year after year and getting all gussied up, which includes wearing nude suits, garter belts, wigs and strap-on slinkies and I won’t say where," said Alzheimer's Association co-chair Laurie Burrows Grad. "They have no shame and for that we love them."

Guests were entertained by a duet by John Stamos and Robert Morse from their musical How to Succeed in Business Without Really Trying while Shoshana Bean reenacted her role as Elphaba to sing "Defying Gravity" from Wicked. Steven Weber tapped into his inner Miss Trunchbull, dressed from the hair bun down to the skirt and tights to perform a number from Matilda the Musical.

Actor Keith Carradine honored Grammy award-winning artist Glen Campbell and his family with the inaugural Glen Campbell Courage award. After being diagnosed with Alzheimer's disease, Campbell chose not to shy away from his disability, embarking on a 151-city tour before currently residing in respite care.

"He can no longer remember any words to any of his songs or play them on the guitar or even tune a guitar," said Campbell's wife Kim Campbell. "He has a hard time communicating in sentences except to say things like, 'I love you.'"

Grammy-winning songwriter Jimmy Webb performed a tribute to the country legend along with Carradine, Grace Potter and Campbell's children Shannon and Ashley Campbell who make up two-thirds of the band Victoria's Ghost. The musicians were later joined by the Big Bang Theory cast as they all tipped their cowboy hats off to Glen, singing his hit song "Rhinestone Cowboy" into the night.
