Veteran singer Frankie Valli has axed a series of upcoming tour dates with the Four Seasons due to illness. The 79 year old is currently touring the U.K. with his band, but they have now been forced to call off four of this month's (Jun13) shows. Concerts in Manchester, Bournemouth and Birmingham in England have all been scrapped, along with another gig in Edinburgh, Scotland (13), and fans will have to wait until later in the year (13) for the rescheduled dates. A spokesman for the band says in a statement, "Shows in Manchester, Edinburgh, Bournemouth and Birmingham will now be re-scheduled in the autumn with new dates to be advised next week. Please hold onto your tickets which will be valid for the rescheduled dates. "Frankie wishes to apologise to all ticket buyers that's he's had to change these dates."
