Tommy and Malcolm Merlyn Sing!

I just discovered that Colin Donnell, who plays Tommy Merlyn in the CW's series, Arrow, is a musical theatre performer. John Barrowman, who plays his father, Malcolm Merlyn, is also a musical theatre performer (among other things, such as Captain Jack Harkness in Doctor Who and Torchwood).

Both Colin and John played Billy Crocker in Anything Goes. Colin was in the latest revival on Broadway with Sutton Foster, and John played the part at London's West End in 1989 and again in 2003.
