andrew/ian,
i was looking at one of those water damaged billboards i looked at to help with the chart positions last month. the april, 23rd 1983 issue in fact. i happened to glance at the boxscore section that week (on page 38) and the beach boys were listed twice. the march 30th show in jackson, mississippi was at the west mississippi coliseum. a group named windows opened the show.
just for trivia it grossed $79,973 with 7,240 tickets sold out of 9,138 available.
the may 7th, 1983 issue had on page 48 the boxscore section. beach boys listed twice. their april 5th and 7th shows were opened by group/person (?) called luba. the april 5th show was a sellout.
just passing along what i see in print.....
