Rock-and-roll artist Bret Michaels will put on the last concert at the Brown County Veterans Memorial Arena April 6th.  The frontman for the group Poison has performed at the soon-to-be-closed Green Bay venue six times previously.  The “Nothing But A Good Time For The Last Time” concert will feature Michaels, his band, Warrant, and Lita Ford.  Thirty years ago the video for Poison’s hit “Every Rose Has Its Thorn” was filmed at the arena.
