If you were hoping to be in the audience when Colbie Caillat and Gavin DeGraw take the stage at Frederik Meijer Gardens this summer, you're probably out of luck. Unless you were one of the lucky Frederik Meijer Gardens members who snagged tickets this past weekend. Tickets for all of the shows that are part of the Summer Concert Series went on sale to Meijer Gardens members Saturday morning, and three of the shows sold out within two hours of going on sale.

In addition to Gavin and Colbie, the Steve Miller Band and Bonnie Raitt managed to sell out in almost record time. Over 28,000 tickets were sold over the course of the weekend.

More than 70 percent of the available tickets for the B-52s - who kick off the series June 1 - Al Green, Darius Rucker, Wynton Marsalis, Lyle Lovett and O.A.R. shows also have been sold.

The members-only presale will last through May 11. Tickets for the general public will go on sale May 12. Members save $5 off the regular ticket price.
