McGillin, a two-time Tony nominee for his performances in Anything Goes and The Mystery of Edwin Drood, plays the venue Aug. 7-8 at 8 PM. "For 54 Below, we've got a show people might not expect to hear from me," McGillin told Playbill.com. "It's a show about challenging convention — breaking the rules. I think the song 'Everybody Says Don't' captures the spirit of the show." Aside from singing, audiences can also expect to see McGillin play an instrument during the solo concert.

McGillin's other Broadway credits include Sunday in the Park With George, Kiss of the Spider Woman, The Secret Garden and The Phantom of the Opera. As previously announced, the singer will join Tony winner — and former Anything Goes co-star — Patti LuPone as well as Norm Lewis and Seth Rudetsky on Playbill's third Broadway on the High Seas cruise.

54 Below is located at 254 West 54th Street. There will be a $30-40 cover plus a $25 food and beverage minimum. For more information and tickets, visit 54Below.com.
