Dylan wanted to go somewhere and sing traditional songs rather than do a big concert. So for the after-party, he and many of the artists went to Tommy Makem's Irish Pavilion club on E 57th Street and sang Irish songs with the Clancy Brothers and Tommy Makem, who had performed at the 30th Anniversary concert by Dylan's request.
Elvis Costello was supposed to appear at the concert to sing a duet of "Positively 4th Street" with Van Morrison; neither artist turned up.
