The legendary session drummer Hal Blaine created the huge drum sound with the help of producer Roy Halee, who found a spot for the drums in front of an elevator in the Columbia offices. As recounted in the 2011 Making of Bridge Over Troubled Water documentary, Blaine would pound the drums at the end of the "Lie la lie" vocals that were playing in his headphones, and at one point, an elderly security guard got a big surprise when he came out of the elevator and was startled by Blaine's thunderous drums.
