From 2000 until 2004 Lockett was involved in a group called "Celebrating The Jazz Couriers", playing the music of Ronnie Scott and Tubby Hayes. The group was co-led by Martin Drew and won the British Jazz Award for "Best Small Group" in 2002. The band was reformed in 2004 as "The New Jazz Couriers".
In November 2008, in conjunction with fellow tenor saxophonists Art Themen and Don Weller, Lockett released the album The 3 Tenors at the Appleby Jazz Festival.[4]
