Bob Henrit was originally the drummer with Buster Meikle & The Day Breakers, together with Russ Ballard on guitar and Roy Ballard, Russ's older brother, on piano. All usually appearing on stage dressed in matching red jackets & was it black collars? Russ left stage, his brother Roy behind him, Bob stage right & Buster singing up front. Cheshunt Boys' Club was a favored gig around '61. He then enjoyed initial success as a member of The Roulettes (1962-1967), who, in addition to a recording career of their own, backed the popular music singer Adam Faith on tour and on record. After the demise of the Roulettes, Bob briefly (1968) worked with Unit 4 + 2, an association which went back to his session drumming on their biggest hit, Concrete and Clay.
In late 1968, Bob teamed up with Russ Ballard, Jim Rodford and ex-Zombies keyboard player Rod Argent to form Argent, and remained with them until the band ended in 1976. After a brief spell with Jim Rodford and John Verity as Phoenix, Henrit's post-Argent career included work with a number of artists, including Charlie, after their 1978 tour opening for The Kinks, and Ian Matthews.
As a session drummer, he worked with The Who vocalist, Roger Daltrey, and was present on Dave Davies' Glamour and Chosen People solo albums. He also worked regularly with the GB Blues Band which, in addition to Jim Rodford, included former members of the Mike Cotton Sound.
Bob replaced Mick Avory as drummer in The Kinks, after Mick's departure in July 1984. He worked with the act until their seemingly final demise in 1996. He was the obvious choice to replace Mick, because he and Jim Rodford had already proven to be a capable and compatible rhythm section, and his previous ties with Dave Davies and with other musicians who had augmented The Kinks over the years.
In January 2007 Mick was unavailable for a Kast Off Kinks gig in Broxbourse, so Bob was enlisted to play drums. Since then he has sat in with them many times at the Fan Club gathering at the Boston Arms, Tuffnell Park, on Dedicated Follower of Fashion, with Mick Avory as lead vocalist, and for a few later-era Kinks songs. Bob also stood in for Mick at several gigs in 2010 and 2011.
In 2010 and 2012 Bob re-joined the original line-up of Argent for UK tours.
