The True hitmakers scrapped two concerts in Italy earlier this month (Aug15) after Keeble was hit with a "sudden illness", and he has not recovered in time for their gigs in Spain this week.

They were scheduled to play at the Festival Porta Ferrada in the Costa Brava region on Tuesday night (18Aug15), Ibiza Rocks on Wednesday (19Aug15) and in Marbella on Friday (21Aug15), but all three shows have now been called off.

A statement posted on the band's website reads, "Cancelling shows is always something that we try to avoid and we are so sorry to let our fans down, but our priority at this time is John's health and his recovery."

Singer Martin Kemp also wrote on Twitter.com, "Gutted to cancel this week's shows but with all the love you guys are sending (Keeble) he will be on the mend soon!"
