VIDEO: Watch Lea Salonga's Full Musical Performance on CRAZY EX-GIRLFRIEND Season Finale

Last night's Season Finale of The CW's CRAZY EX-GIRLFRIEND Season Finale featured Tony Award winner Lea Salonga (Broadway's ALLEGIANCE), performing "One Indescribable Instant" and Donna Lynne Champlin's "After Everything I've Done For You". Watch both performances in full below!

In the musical-themed comedy, Rachel Bloom stars as Rebecca Bunch, a successful driven, and possibly crazy young woman who impulsively gives up everything in a desperate attempt to find love and happiness...in suburban West Covina, CA.

Tony nominee Santino Fontana plays Greg, a bartender and Rebecca's (Bloom) first friend. The cast also includes actor and comedian McDonald (MADtv) as Darryl, Rebecca's new boss; OBIE and Drama Desk Award winner Champlin (Broadway productions of Billy Elliot, Sweeney Todd) as Paula, her co-worker at the law firm who is suspicious of Rebecca; and Broadway star Rodriguez III (Here Lies Love) who plays Josh, Rebecca's childhood boyfriend who she serendipitously runs into years later, and who acts as the catalyst for her dramatic life change.
