Tonight is the night the Def Leppard and Motley Crue rock to the stage at Dublin's Marlay Park, as part of their joined World Tour.
This tour has seen the bands take in shows across South America, US, and Europe this year.
A world tour which began in Mexico City on February 18 of this year, has also seen them kick off the European leg of this tour at Sheffield's Bramall Lane on May 22.
Having performed at this year's Lytham Festival a few days earlier, Def Leppard and Motley Crue take to the stage at Marlay Park tonight.
This show will see Mammoth WVH who are fronted by Wolfgang Van Halen, the son of rock legend Eddie Van Halen, warm up the Marlay Park stage beforehand.
At the time of writing this piece, some tickets remained available via Ticketmaster. More on this here.
What sort of live set can we expect from the bands? Well, Def Leppard and Motley Crue appear to be taking turns over who plays first.
Both seemed to be playing 90 minute sets. Here are the sets performed by the pair at a concert last week.
