Lennox signed provisional forms for Celtic in September 1961 and made his first-team debut the following March.

He was an extremely fast winger and he was known by fans as 'Buzz Bomb' or 'Lemon' since he made defenders look like 'suckers'.

Though not a forward, Lennox had an incredible goal scoring record - 272 goals in 537 domestic League and Cup games for Celtic. A classic moment in his career was his goal for Scotland against the world champions, England, at Wembley in 1966-7.

He won ten full caps for Scotland in all and made three appearances for the Scottish League.

Lennox left Celtic in the late 70s and moved to the US to play for the Houston Hurricanes. During the 1978 season, he scored 15 goals in 36 games, before returning to Celtic in 1979. It was a worthwhile move as Celtic took the League Championship that year and the Scottish Cup in 1980.

He also won a European Cup winners' medal, nine Championship badges, eight Cup winners' medals and four League Cup winners' medals and was awarded the MBE in 1981.
