PHOTO CALL: Annaleigh Ashford, Laura Benanti, Lesli Margherita, Morgan James, Nick Adams and Roe Hartrampf Strip Down With the Skivvies

Tony Award winner Laura Benanti and Tony nominee Annaleigh Ashford joined The Skivvies for a late-night Nov. 9 concert at 54 Below.

Featuring actor-musicians Lauren Molina ( Sweeney Todd, Marry Me a Little) and Nick Cearley ( All Shook Up), the Skivvies are known for their acoustic performances of pop songs, wearing nothing but their underwear. The duo and their guests play instruments ranging from the cello, ukulele, guitar and glockenspiel to the melodica.

The 11 PM concert featured Benanti ( Gypsy), Ashford ( Kinky Boots), Lesli Margherita ( Matilda), Morgan James ( Motown) and Roe Hartrampf ( Nobody Loves You).

The Skivvies recently shared their ideas for stripped-down, Broadway-inspired Halloween costumes. Check out the photos here.
