The Drinkwater Twins at 54 Below

I saw the Twins (John and Matthew) last Thursday at 54 Below playing the Boys in THE BOYS FROM SYRACUSE. The score, of course, is fantastic, and the evening was enjoyable enough ( Christine Pedi sang one number, after all), but the Twins were absolutely winning and delicious. There were no programs, of course, and from what I can see online it seems they haven't yet done much beyond school musicals (NINE!, be still my heart) and cabaret shows (lots at Birdland). I'm curious if anyone has seen either of them in a staged professional production or know what might be in store for them in the near future.
