We All Make Mistakes

Riddle: A young, aspiring musician who lived on a farm, had been given the task of monitoring the family’s livestock. The young lad was supposed to see to it that the cows and sheep stayed together as they had been trained to do, but unfortunately, as youngsters often do, he allowed himself to drift off and fall asleep beneath a pile of animal fodder, and as a result, the cows wandered into a field of corn, while the sheep made their way into a grassy meadow. Can you identify this irresponsible youth?
