The cast of "Glee" managed to be cuter than usual yesterday -- and it was all for a good cause.

Matthew Morrison, Cory Monteith, Chris Colfer, Mark Salling, Jenna Ushkowitz, Jayma Mays, Harry Shum Jr., Dot-Marie Jones and Romy Rosemont were all part of a huge charity event to benefit students in disadvantaged schools in the L.A. area.

The cast teamed up with American Express, TakePart and Education Through Music and took time to make handmade musical instruments with kids yesterday during a volunteer event on the Paramount lot, where "Glee" films.

The event ended with AmEx donating $100,000 to Education Through Music, which promotes music education at schools.
