Are you sure it was Fort Wayne? The giant inflatable juke box was used on the "4" tour in 1981-1982. My records indicate that Foreigner played the following Indiana dates on that tour:
November 9, 1981: Roberts Memorial Stadium, Evansville, IN
November 11, 1981: Market Square Arena, Indianapolis, IN
December 13, 1981: Convocation Center, Notre Dame University, South Bend, IN
The ND Convocation Center and Roberts Memorial were smaller venues, capacity about 11,000. Market Square of course was a big, NBA-size arena, capacity of 18,000. My records also show that the Market Square show was sold out whereas the other two were not.
I also checked the Agent Provacateur tour in 1985, and the band played both Evansville and Indianapolis, but not Fort Wayne.
Hope this helps.
I went to a Foreigner concert in the early 80's in Ft. Wayne. I went with my high school girl friend (now wife) and I am trying to figure out the date as part of a birthday present.
The show was in a large venue (maybe the colosseum) and there was a giant inflatable juke box for Juke Box Hero.
Any help at all would be appreciated!
