In 1959, he appeared in The Pleasure of His Company and The Golden Fleecing at the Omaha Community Playhouse, and in 1962 he appeared in Under the Yum Yum Tree at the Mineola Playhouse and in Louisville. In Mineola, the other leads were Margaret O'Brien and Hugh Marlowe. Don't know if they were also in it with him in Louisville. That's all I'm finding in a couple of quick searches, but perhaps there was more.
Linking a photo of him and John McMartin in Blood, Sweat and Stanley Poole.
