It’s not as major-league as Paul McCartney at Target Field, but Twin Cities rock fans will still consider the Replacements’ long-awaited hometown reunion concert at Midway Stadium on Sept. 13 a grand slam. Tickets for the show – billed as their “homecoming concert” – will go on sale next Saturday, May 3, at 10 a.m. for $50 through eTix.com, the stadium’s box office and First Avenue outlets.
