What DJ played before U2's "Zoo TV" shows?

B.P. Fallon played before U2’s Zoo TV shows.

Fallon was an Irish rock journalist, broadcaster, photographer, and DJ who became part of the tour’s deliberately chaotic multimedia atmosphere. During the 1992 legs of Zoo TV, he played records for the audience from inside a Trabant car positioned on the B-stage. He also delivered commentary while wearing a cape and top hat, using the official title “Guru, Viber and DJ.”

His role was more theatrical than that of a conventional support-act DJ. Fallon had originally been hired to write the Zoo TV tour programme, but he became a visible onstage personality and hosted Zoo Radio, a 1992 radio special featuring U2, opening acts, interviews, and unusual audio material.

The answer can be confused because other DJs also appeared during the tour. Paul Oakenfold and Colin Hudd replaced Fallon at later points, while 1993 dates featured performances by the Irish theatre group Macnas. For the question’s standard reference to the pre-show DJ associated with Zoo TV, B.P. Fallon is the canonical answer.
