“How the Heck Did I Get Here?” That’s the jolly, mystified title of James Monroe Iglehart’s lighthearted show at Feinstein’s/54 Below, in which he traces his path from a choirboy growing up in Hayward, Calif., to Broadway glory. Two years ago, Mr. Iglehart, 42, won a Tony Award for best featured actor in a musical as the Genie in “Aladdin.” His show on Monday evening was a casually friendly career survey devoid of the preening grandiosity that often accompanies such autobiographies.

Although Mr. Iglehart’s style has veered in several directions, his roots are in gospel. In his most impressive performance, of the James Cleveland standard “I Don’t Need Nobody Else (as Long as I’ve Got Jesus),” the club momentarily became a church, and Mr. Iglehart and his band, led by the keyboardist and musical director Bill Sherman, were completely at home. At moments like those, the show reminded you how sanitized Disney songs like “Friend Like Me,” his signature number from “Aladdin,” are secular gospel songs.
