From a studio at the top of the stand named in his honour, Alan Curbishley is recounting the day a record crowd came to The Valley and he sat on the stage watching The Who performing to an estimated 88,000 people.
He was 16 years old and a month from joining West Ham as an apprentice, and he spent the morning making pin badges on a small machine and selling them to gig-goers for 20 pence apiece.
