What's more someone has sent a couple of photos taken there. One of Hazlewood himself:
... and one of his guitarist Al Casey (1936-2006), who also played with Elvis Presley and Johnny Cash among many others.
Hazlewood played some of his last major gigs at the Royal Festival Hall in 1999, 2002 and 2004. Hazelwood seems to have rehearsed at the Music Room for both of the last two of these, with my informant stating that he liked drinking in The Five Bells. These photos were taken in 2002, with the person who sent them stating that 'He was an utter gentleman to work for, completely charismatic, his unique talents undimmed'.
