Ringo Starr has cancelled the last five dates of his current North American tour, after contracting COVID-19 for a second time in the span of a fortnight.First testing positive for the virus at the start of October, the Beatle was forced to cancel seven shows between Michigan and British Columbia. He returned to the road on Tuesday (October 11) – flanked by the All-Starr Band – performing in Seattle then and in Portland the following night (October 12).It appears that his comeback was premature, though, as Starr has now confirmed he’s again returned to being COVID-positive.
