London's hidden museums and libraries
The quirkier and unsung enclaves of curios in the capital
The Hard Rock Café seems a more-than-obvious choice for music nostalgia, but to serious musos it's the height of naff. However, beneath the tourist-friendly gift shop there lies a boudoir packed with enough memorabilia to impress even the most hardened cynic. The Vault is open seven days a week and gives you free access to rock artefacts like John Lennon's hand-corrected lyrics for 'Imagine' and Madonna's conical, comical 'Blonde Ambition' bustier.
