Footage surfaces of Jay Z onstage during his Magna Carta world tour and he struggles to recall the lyrics to Drake's "Pound Cake."

In the video, the beat drops and he pauses before he picks up his microphone. Holding his chin in a pensive stance, Jay tells the DJ to cut off the song and he spits a verse of "Dead Presidents" acapella. Later in the video, Jigga picks up where he left off and he performs his verse to "Pound Cake."

This video makes you wonder if Jay needs a little more sleep because he totally blanked out when it was time for "Pound Cake."

Here's the video and you are more than welcomes to conjure up your own assessment.
