Cast members of "Glee" pose with the Yale Whiffenpoofs.

The Yale Whiffenpoofs will once again bring their a cappella talents to the small screen when they appear in the Season 4 finale of “Glee.”

The show will air on Thursday, May 9, at 9 p.m. (EDT and PDT) on the FOX network.

The Whiffs already have a tie with “Glee”: The ensemble has performed in two benefit concerts with “Glee” cast member Darren Criss — a 2011 fundraiser for the Elizabeth Glaser Pediatric AIDS Foundation and the Trevor Project, which provides crisis intervention for lesbian, gay, bisexual, transgender, and questioning young people; and an April 14 performance supporting P.S. Arts, which helps bring arts education to underserved public schools.

“Glee” is just the latest in a string of television appearances for the Whiffs. They have also performed on “The West Wing,” “Saturday Night Live,” “Gilmore Girls,” “The Sing-Off” and “Jeopardy!”
