Gregory on Broadway
Simonson, a member of the venerable Steppenwolf Theatre in Chicago, has premiered many of his plays there.
In addition to understudying Tug Coker, who starred as Larry Bird, Gregory covered Peter Scolari, who played Auerbach, Riley, Buss, and two other parts. Scolari is best known for playing Tom Hanks's best friend in the sitcom Bosom Buddies.
