Are you a good karaoke singer? Are you good at singing Beyoncé karaoke songs specifically? Does your voice translate well over the phone? Well, it’s your lucky day! A kind Beyhive member is giving away their treasured, signed 2012 Beyonce concert poster for free. What’s the catch you ask?

The winner must sing a no holds barred, really going for the gusto version of “Single Ladies” into this person’s voicemail by 4 p.m. That’s it. This gem of a human being is just trying to pay it forward before they move into a new home. It looks like this Craigslist ad was posted yesterday, so we might being singing for naught, but it's worth a try, no?
