The hit parade turns 60! On 14 November 1952, NME published the first UK singles chart. "Here in My Heart" by Al Martino was No 1. To celebrate the 60th anniversary, The IoS asked 60 of Britain's leading personalities to name their perfect record, and explain why. The twist: they had to tell us in 140 characters or fewer. Join our Twitter campaign and tell us your favourite chart sensations! The full list is available in today's edition of the Independent on Sunday. Individual selections from our singles chart survey will be tweeted from @IndyOnSunday throughout the day. Look out for #60hits and share your own favourites online. Enjoy!
