 The Luton side first played in the white and black colours which it has retained for much of its history during the 1920 – 21 season , when the club rejoined the Football League ; the players had previously worn an assortment of colour combinations , most permanently sky blue shirts with white shorts and navy socks . Such was the quality of Luton 's team at this time that despite playing in the third tier , a fixture between Ireland and England at Windsor Park on 22 October 1921 saw three Luton players on the pitch — Louis Bookman and Allan Mathieson for Ireland , and the club 's top goalscorer , Simms , for England . However , after Luton finished fourth in the division , the squad was broken up as Simms , Bookman and Mathieson joined South Shields , Port Vale and Exeter City respectively . Luton stayed in the Third Division South until 1936 – 37 , when the team finished top and won promotion to the Second Division , at that time the second tier of English football . During the promotion season , striker Joe Payne scored 55 goals in 39 games ; during the previous season he had scored 10 in one match against Bristol Rovers , which remains a Football League record today .
