Michael Carroll is to be tried at Norwich Crown Court
Carroll, 22, admitted affray along with David Howard, 24, both of Downham Market, after a fight at the local Christian Fellowship in May 2004.
Both had initially denied affray and were due to stand trial. On Thursday Carroll also cancelled his legal aid.
Two teenage girls, who cannot be named, denied affray but admitted using threatening behaviour.
All four were granted bail and are due to be sentenced on 10 February.
On Thursday, Carroll's defence, Ben Smitten, said Carroll had "instructed the legal aid order to be cancelled and had discharged those lawyers because of adverse publicity".
A fifth man Paul Howard, 19, of Swaffham in Norfolk, had admitted affray and was sentenced to six months in a young offenders' institution in September 2004.
