On May 16, Rick Allen, Vivian Campbell, Phil Collen, Joe Elliott and Rick Savage will be in conversation at the Royal Festival Hall, talking about their incredible life in music, and their new book telling the tale - Definitely: The Official Story Of Def Leppard, published by Genesis Publications.

Tickets to the event can be purchased via the Southbank Centre website, here. Especially for the event, copies of Definitely: The Official Story Of Def Leppard that are bought in advance as an optional add-on are available at reduced price of £30 and will come with an exclusive commemorative event poster featuring a new portrait of the band taken by the rock photographer, Ross Halfin.

"We had balls and we were naive, in a good way. We just went out there, full throttle..." - Joe Elliott

Released as a hardback, priced £35, on May 18, Definitely: The Official Story Of Def Leppard is the ultimate record of Def Leppard's legendary career and is available to order from defleppardbook.com and all good bookstores. A signed limited-edition version became the fastest-ever title to sell out in Genesis Publications’ history, after it was fully subscribed within days of its pre-order announcement.

Part memoir, part scrapbook, the wide-ranging narrative from the band chronicles Def Leppard's incredible story through hundreds of photographs where fans can reminiscence on the band recording in various studios, at promo shoots, on tour in planes, trains, cars and Holiday Inns, backstage and, of course, doing what they are best known for - performing their explosive live shows in front of global audiences from 1978 to the present day.

From extensive new text contributions to in-depth archival interviews, every member's voice is present within the book including Joe Elliott (lead vocals), Rick Savage (bass and vocals), Rick Allen (drums), Phil Collen (guitar and vocals), Vivian Campbell (guitar and vocals), Tony Kenning (drums), Pete Willis (guitar) and Steve Clark (guitar). Definitely also features introductions by Queen founder and guitar maestro, Brian May, and renowned journalist and senior editor of Rolling Stone, David Fricke. A long-time friend and champion of the group, Brian May delivered the speech for Def Leppard's induction into the Rock & Roll Hall of Fame in 2019, while David Fricke has written about the band from their earliest successes.

"Def Leppard are original, inimitable and, well, I'm gonna say immortal." - Brian May

Photographs from band members' personal archives and fans across the world are featured alongside those taken by renowned rock photographers such as Ross Halfin, Mick Rock and Anton Corbijn.
