In celebration of Liza's birthday, the duo joined forces last night at The Town Hall to sing familiar songs from 'Cabaret' and Liza dipped into her repertoire of signature songs known the world over. Alan performed his renditions of songs - from Annie Lennox to his own original compositions. BroadwayWorld was there for the special event and you can check out photos from the after party below!
