Post break-up

Dave Clark was also the manager of the band.

Bobby Graham, a well-known British session drummer in the 1960s, claimed in 2004 that he, rather than Clark, played on all of the group's hit records . However, Ron Ryan, in a 2006 interview, insisted that Clark definitely played drums on all the recordings, except on the rare occasion when he could not produce and play at the same time. However, Ryan was not associated with the group when it was recording its biggest hits from 1964-67 and has no firsthand knowledge of the recording process on those tracks.

Clark was notorious for having a closed studio, primarily to protect the secret that accomplished session players were used on the records. Ironically, most session drummers would not want to be known as the real Dave Clark, as Clark was not a skilful drummer. He was however, a successful businessman, entrepreneur, producer and promoter - and in those capacities, he was indispensable to the success of the group.

Following the break-up of the band, Clark set up a media company. In the process, he acquired the rights to the iconic '60s pop series Ready, Steady, Go!.
