Brian began playing double bass in several bands, notably with the Lincolnshire based rocker Vince Eager (born Roy Taylor, 4 June 1940, in Lincoln). He switched to bass guitar, later joining The Wildcats, a backing group for the rock and roll singer Marty Wilde. A fellow Wildcat was the drummer and future Shadow, Brian Bennett.
He also played several other instruments, including harmonica which he has always featured and clarinet (nicknamed the "licorice stick"), which earned Locking the nickname "Licorice". When Marty Wilde parted company from The Wildcats, they changed their name to "the Krew Kats" and recorded instrumentals with modest success.
In April 1962, at Bennett's suggestion, Licorice was himself invited to join The Shadows to replace the departing Jet Harris and played on some of their best known tracks, including "Dance On", "Foot Tapper" and "Atlantis". He also played the harmonica in live shows and on his signature album track, "Dakota". He appeared in the Cliff Richard film, Summer Holiday.
