by James ChrispellWhen you latch onto a hit formula, don't mess with it, and that is just what the doctor ordered with Desitively Bonnaroo. With installment number three of Dr. John's funky New Orleans-styled rock & roll, trying to strike gold again proved elusive. There wasn't the big hit single this time around to help boost sales, and the tunes were starting to sound a little too familiar. While not a carbon copy of his previous releases, Desitively Bonnaroo was a disappointment to his fans. Good as it was, it was the end of an era for Dr. John and his type of music.
