The Minnesota State Fair filled in the missing names on its grandstand entertainment lineup this morning, and only two of the three shows are all about nostalgia acts.

The previously leaked Aug. 24 stop on Sammy Hagar's Four Decades of Rock Tour was confirmed alongside an Aug. 23 date with the Under the Sun Tour featuring '90s one-hit wonders Smash Mouth, Sugar Ray and Gin Blossoms. One of last year's Basilica Block Party headliners, Train, took the Aug. 29 slot with another BPP alum, Michael Franti & Spearhead. Tickets for all the shows go on sale Saturday. Here's the rundown on each show:
Train with Michael Franti & Spearhead -- 7:30 p.m. Thursday, Aug. 29. Tickets are $47 and $37 and go on sale at 10 a.m. Saturday, June 15.

Under The Sun featuring Smash Mouth, Sugar Ray and Gin Blossoms -- 8 p.m. Friday, Aug. 23. Tickets are $28 and go on sale at 11 a.m. Saturday, June 15.

Sammy Hagar's Four Decades of Rock with opener Buckcherry -- 7:30 p.m. Saturday, Aug. 24. Tickets are $35 and go on sale at noon Saturday, June 15.

Meanwhile, a few noteworthy names were added to two of the previously announced concerts already on sale: The MN Music on a Stick concert with Trampled by Turtles, Mason Jennings and the Chalice on Aug. 30 will also now feature P.O.S. and the Suburbs, which ups the value of that one twofold.

Also, influential Brooklyn rap vet Talib Kweli has been added as an opener to Macklemore & Ryan Lewis's long sold-out gig on Aug. 31 along with buzzing young Chicago star Chance the Rapper.
