I was 14 and went to this show with no adult supervision…
U2 had reached the level of popularity where a Forum show was possible but had not yet broken out into widespread fame and familiarity among the general rock and pop audience; that would come in 1987 with the release of The Joshua Tree. The Unforgettable Fire Tour popularity level is sometimes referred to as “mass cult”, and is similar to, say, what Bruce Springsteen had on his River Tour before Born in the U.S.A. or what Metallica had on their Damaged Justice tour before their Black Album. It made for intense concerts in this instance, because it provided a very large but fully devoted audience, with fans standing on chairs for the entire performance and continuing “40” refrains long after the show was over.
