Finn had another Broadway success with "The 25th Annual Putnam County Spelling Bee", for which he wrote both music and lyrics. The show won two Tony Awards in 2005-one for Best Book of a Musical, and another for the Best Performance by a Featured Actor in a Musical. It ran Off-Broadway, then on Broadway in 2005 and toured the United States in 2006. The show was first workshopped and produced at Barrington Stage Company (BSC) in Pittsfield, MA, where Finn later created The Musical Theatre Lab (MTL) with BSC Artistic Director Julianne Boyd. The MTL is an annual summer lab where emerging musical theatre artists are supported and new musical works are created, fine-tuned and produced under the curatorship of Finn and Boyd.
