‘Barbara Windsor smacked our bottoms!’ Pet Shop Boys on showstopping visuals, horrified bosses – and snubbing the queen

As a 600-page doorstopper celebrates their groundbreaking costumes, gigs, sleeves and videos, the duo talk about ‘side-stepping the pop-star thing’ – and the naked trampolinist EMI had to censor

In 1988, when he was 20, Wolfgang Tillmans tore an A0 poster off a building site hoarding and nailed it to a wall in his flat in Hamburg. It was advertising Pet Shop Boys’ new album, Introspective, and consisted of thick vertical bars in different colours. “It was just so cool in the context of the time,” the artist says today, admiring how the pop group had gone “one level more abstract”.

Around the same time in Doncaster, teenager Alasdair McLellan – now an A-list fashion photographer – was impressed by the clothes of Pet Shop Boys’ keyboard-player Chris Lowe; for instance the cap, stripy T-shirt and Issey Miyake glasses on the cover of their single Suburbia. “I always thought he was the best-dressed man of the 80s,” McLellan says. “Obviously, he just stood there playing the keyboard and I always noticed what he was wearing, especially all that sportswear stuff. He just seemed to do it better than everyone else.” McLellan couldn’t get style magazines in his village, so his visual education came from pop and the music press. “I got into photography through album covers, Smash Hits and NME.”
