Brian Cowen later joined Alan Duncan ,John Coulthard and Keith Wilkinson and Brian Oliver in The Chains (shown above left). On the right the two Brians.

Brian Cowen eventually left the Chains in mid 1965. He was replaced by Ray Parr and the band became The Troubles. The lineup was John Coulthard (piano/vocals), Alan Duncan (drums), Brian Oliver (bass/lead vocals) and Ray Parr (lead guitar/vocals).

When Ray Parr left The Troubles the band split up and Brian Oliver joined Norman's Conquest for a while, playing bass.

Later John Coulthard, Alan Duncan and Brian Oliver teamed up with Neil Marshall on bass, Brian switching to 6-string guitar. This new lineup led to the birth of 22nd Street People in August 1966 when they discovered their voices blended well for 4-part harmony and a West Coast "sunshine pop" sound.
