Imagine if you were at your school fundraiser, and one of the mums got up onstage and started warbling out a bit of Whitney as a "surprise"... Nine times out of ten, it wouldn't end well, and there'd be a fair amount of eye watering all round.
Unfortunately, not everyone goes to school with Beyonce's daughter, Blue Ivy - otherwise, you'd be guaranteed pitch perfect performances every time. To quote the person taking the below vine: "Where am I right now?!"

It wasn't the only ditty she performed after turning up to "surprise". Melanie TV put together this montage of her performance on Youtube: "Beyonce made a surprise appearance at a benefit event for Blue Ivy’s elementary school in Los Angeles on Saturday, March 5, showing off her dance moves and her vocal finesse for the parents, faculty and supporters in attendance."
