Watch Alan Cumming Cover Adele and Hedwig at XL Nightclub & Cabaret

Alan Cumming is best known for his Tony-winning portrayal of the Emcee in the Broadway revival of Cabaret, but on March 17, the Broadway vet revealed his inner pop diva. The actor performed a concert benefit at New York's XL Nightclub & Cabaret, with proceeds going towards the Gay and Lesbian Human Rights Commission. After singing a medley from the 1998 off-Broadway hit Hedwig and the Angry Inch (accompanied by piano and cello), the current Good Wife star pulled out all the stops in his grand finale. The actor sang an emotional rendition of Adele’s “Someone Like You” that gives the Grammy winner a run for her money! Click below to see Cumming wow the crowd on this one-night-only event.
