Jonny Griffin was a legendary tenor sax player, known as ‘Little Giant.’ He played at Ronnie Scott's in 1964, backed by members of Ronnie's House Band (Stan Tracey, Malcolm Cecil and Jackie Dougan). Val Wilmer took this in Trafalgar Square and it became the album cover for the live recording, which was re-mastered from original tapes recorded at the club by Les Tomkins.
