Are you pining for Def Leppard already? The British rockers, who played at Xcel Energy Center last October, are returning to the X on April 21.

That, of course, is the first anniversary of Prince's death and there will be big festivities at Paisley Park. But that's another story.

As always, Def Leppard believes in bang for your buck. Poison and Tesla will open.

Last fall, Tesla and REO Speedwagon opened for the Leps. In 2015, Styx was with Def Leppard at the State Fair. In 2014, Def Leppard teamed up with Kiss at Target Center.

The "Pour Some Sugar on Me" hitmakers are touring to promote a new live DVD, "And There Will Be a Next Time: Live from Detroit," due Feb. 10.

Tickets for the St. Paul concert will go on sale at 10 a.m. Jan. 21 at the X, Ticketmaster and Live Nation outlets.
