As a reporter on UK music weekly Melody Maker, Chris Welch went on the road with Led Zeppelin during the early 1970s and saw Robert Plant, Jimmy Page, John Paul Jones and John Bonham in close-up action at their most exciting and historic shows.

Chris has since worked on a variety of music magazines and has written more than 20 books on rock music. He also contributes to UK newspapers. His finest hour was "Playing conga drums, live on stage in Germany with Led Zep during 'Whole Lotta Love'."

Hugh Fielder can remember the 1960s even though he was there. He can remember the 1970s and 1980s because he was at Sounds magazine (RIP) and the 1990s because he was editor of Tower Records' TOP magazine. He has shared a spliff with Bob Marley, a glass of wine with David Gilmour, a pint with Robert Plant, a cup of tea with Keith Richards and a frosty stare with Axl Rose. He has watched Mike Oldfield strip naked in front of him and Bobby Womack fall asleep while he was interviewing him.

Barney Hoskyns is the co-founder of online rock-journalism library Rock's Backpages, journalist for Uncut, The Observer Music Monthly and other UK publications, and author of several books including Waiting for the Sun: Strange Days, Weird Scenes, & the Sound of Los Angeles (1996), and Hotel California: Singer-Songwriters & Cocaine Cowboys in the LA Canyons (2005). He lives in London.
