Vanderbilt Student — I BOMBED Calc Test After My Billy Joel Duet

Jamming out with Billy Joel is terrible for your report card … just ask the Vanderbilt freshman whose impromptu duet with the Grammy-winning singer cost him a passing grade on a calculus test.

In case you haven”t seen the video — Billy was at Vanderbilt in January for a Q&A … and a student named Michael Pollack mustered the testicular fortitude to ask to play piano for Billy while he sang “New York State of Mind.” Billy agreed … and the footage is incredible. Pollack KILLS it.

But the adrenaline rush was so big … Pollack tells our sources, he couldn”t get himself to concentrate on studying for a big calculus test. The next day, Pollack says he failed the test with a 69. 

Pollack tells us, “I”m pretty good at calculus, but it was hard to focus when you perform with your idol … I have no shame. I got a 69 on the test, compliments of Billy.”

We”re not worried either … as Billy told Michael on stage, “I think you”re gonna do fine.”
