Every time I hear that song now, it reminds me of the place where I worked back in those days. I remember walking down the hall at the office and hearing that music coming from a side office. I took a step back, popped my head in to listen, and discovered that what I was hearing was not, in fact, the same song. The sales manager had his radio tuned to a classical music program on NPR, and the program's theme song was Beethoven's "Sonata No. 8 in C Minor, Op. 13 (Pathetique Sonata), Mov. 2." Same melody, different century. Beethoven did it first. I love this version almost as much.
