I think you have to be of a certain vintage to appreciate Quo in their waistcoated Telecaster prime, of which he was integral, as the obituaries state. Not bad when you consider their 60s material which looked pretty destined to rank as pop oddities.
I remember seeing him on some TV programme saying 'Marguerita Time' was pretty much why he called it quits.
