Tim Waurick might have the best voice in barbershop. Generally, he sings tenor for Vocal Spectrum, but he took the lead on this song.
His range is remarkable. He could sing any of the four parts in a quartet. He's been singing tenor for Vocal Spectrum for years, and in this video he proves he could handle lead, but I've also heard him sing the baritone and bass parts of songs flawlessly. He's a really remarkable talent.
