Our heart goes out to slow-moving Donnie & Marie fans who can’t get tickets to their sold-out show at Horseshoe Casino. She’s a little bit country, he’s a little bit rock-and-roll, and when you’re a toothy brother and sister act with that kind of range, fans of your weird, ’70s-era TV show will come pouring out of the woodwork. But there’s still plenty of good news for vintage music fans still looking for something to do on July 6th. If you can’t see Donnie and Marie in Mississippi, the Def Leppard and Journey double concert at the FedExForum promises a similar experience, but with a clever twist. Journey’s a little bit classic rock while Def Leppard’s also a little bit classic rock.

Nothing can erase the bitter sting of not getting to hear Donnie and Marie sing their hit song about the girl no one knows (from the poor side of town) and the boy no one knows (from the rich side of town) who, while suffering the pangs of anonymity, both enjoy the benefit of never getting wet when it rains, because love is their magical umbrella. But maybe Journey can scratch that itch with their inescapable mega-hit “Don’t Stop Believing,” and its unlikely story of a city boy and small town girl who both take completely different midnight trains going to the exact same non-place.

Def Leppard lacks the Osmonds’ toothy wholesomeness but make up for it with raunchy MTV-era hits like “Pour Some Sugar on Me” and the hair-metal anthem, “Rock of Ages.”

It’s summer. It’s hot. Go get some nostalgia to feel nostalgic about later.

Def Leppard and Journey at the FedExForum Friday, July 6th, 7 p.m. Tickets from $45.
