Bill & Cory from Practically Single are this week’s guest on Cellar Sessions. Hear their philosophy on performing sober, get some tips on alternative uses for pizza boxes, and learn about the woes of drunken sleepwalking. They perform ‘Bite My Tongue and Come Under’, a modish acoustic version of Rihanna’s ‘Umbrella’, and premiere ‘All My Exes’ off their forthcoming album.
