Jack Emblow, now in his late seventies,but doesn't look it, still performs today and is one of Britain's finest accordionists. The Jack Emblow Sextet was formed in the mid-fifties and gave hundreds of broadcasts, many of them in 'Music While you work' and 'Morning Music'. Although highly regarded among professionals,he remains self-effacing and seemingly unaware of just how good he is! His arrangements for his sextet were outstanding, yet he discarded them when broadcasting dried up. He can still be heard in 'Summer Wine'
playing in the accompanying orchestra - and yes, there is a harmomica in the scoring,which I think is played by Harry Pitch.
