Well, my self conducted Beatallica-thon may be over, and Beatallica's website may not be back online, but the music, it is a returning. I've finally located the song I was looking for, "Hey Dude", the parody of the Beatles "Heh Jude" done in Beatallica's loving Meatallica style. I am quite pleased, but won't be fully pleased untill Beatallica.org returns in all its former glory. My lighter burns for thee.
