The first 4 dates of the Who US tour scheduled to start this week were cancelled a few days ago due to an unspecified illness. Friday (9/18), the group announced that the entire tour is being put on hold due to what the band web site says is a 'mystery virus' Roger Daltry has contracted that has apparently been identified as viral Meningitis. The diagnosis will also result in the lead singer missing the Teen Cancer America benefit concert in Los Angeles for the organization that he and Pete Townshend have long supported. The outlook for Daltrey is good. He wrote, 'I am now on the mend and feeling a lot better but I am going to need a considerable time to recover. The doctors tell me I will make a complete recovery, but that I should not do any touring this year.' Townshend indicates that they hope to schedule make-up dates for the spring of next year.
