Status Quo manager Simon Porter says: "Rick is extremely disappointed to be unable to be part of the tour but, as you will have read, he is acting under medical orders and quite rightly is putting his health first and foremost.
"The band – with Rick’s total blessing – have opted to honour all existing commitments and the reaction from both fans and promoters during Quo’s recent summer shows is that the band has continued to perform as brilliantly and as powerfully as ever.
"A small handful of fans have requested refunds on the forthcoming winter tour and although they actually purchased tickets to see a band rather than a solo performer, we will honour their request for a refund on this occasion purely as a gesture of goodwill and on an ex gratia basis."
