They are all super talented singers, but the guy to watch out for in this video — an incredible 28-song medley of Beyonce’s greatest hits  — is the guy in the top, left-hand position. He actually does the majority of the Bey vocals, and can hit some incredibly high notes. Now, excuse us while we listen to IV  on repeat for the next three days. Viral components: • A cappella! • All the Beyonce you could ever want, like, ever • So much sass. Just, so much of it Verdict:  We don’t think you’re ready for this jelly. with courtesy from Ask.Com
