Independent label: Lucky Records is by far the most obscure. It managed at least two singles. One was a double-'A'-side single split between two speedway-stars-turned-singers Reg Luckhurst and Malcolm Brown.  For both Brown's 'Another Spring' and Luckhurst's 'Speedway', backing was provided by Ken Mackintosh and his orchestra.  The single, which was released in 1974, had a catalogue number of RC-1010 / 1011, each side having its own number. There had been at least one previous release on the label: Malcolm Brown's 'No One But You' (RC-1001; 10/73), Distributed By Lucky Records.
