What the hell are they doing? All I hear is laughing and weired noises and in a weird voice Dan saying "Until The Day I Die." Also, who was doing back-up vocals for the song? Other bandmembers or from a computer? I am confused.
The guys were just playing around with a voice changer. I think it was just Phil and Dan saying stuff. Do you want to know exactly what they said? The people doing backup vocals are Toby Morse from H2O, Ray Kappo, and John Feldmann.
