Bob Seger and the Silver Bullet band make their first Michigan appearance in over five years tonight at the Dow Events Center in Saginaw.  If you want to catch the Detroit rocker at his Saginaw visit, you'd better move fast.  Bob Seger's people have just released 114 tickets -- $69 each -- to the March 29 concert in Saginaw. The 7:30 p.m. show sold out in minutes when it first went on sale weeks ago.
