Unlike many of their Liverpool contemporaries, they specialised in a Chicago blues / Muddy Waters / Bo Diddley / Bobby Bland style of rhythm and blues - a genre of music which was more popular in Southern England at the time, led by the up-and-coming Rolling Stones.

They were invited to support The Beatles on their last Cavern gig on 3 August 1963 and, on 28 February 1964, were on the bill of the first annual British Rhythm and Blues Festival held in Birmingham.

Two trips were made to Hamburg's Star-Club, first over the Christmas and into the New Year period of 1963 / 64 and again during July / August 1964.

Their second Star Club Records release - recorded live on-stage in front of a Star-Club audience - reflects a move towards a more contemporary soul / blues sound in the manner of James Brown and was very much facilitated by the sax sound of Johnny Phillips and Nick Carver.

Mike Hart left the band to pursue a solo career, recording two albums for John Peel's "Dandelion" label.

In an article [1] published in the Liverpool Post newspaper, 31 May 2011, poet Roger McGough stated that his and the Beatles' favourite band of the time was the Roadrunners.
