According to CNN, the last six tour dates for Elvis Costello's European tour have been cancelled.
A statement posted on Costello's website stated he is recovering from surgery to treat cancer.
The 63-year-old musician had the surgery six weeks ago, and it was successful, but it will take a bit longer for him to recover his strength.
Costello wrote that the operation's success had him fooled into thinking that he could resume touring quickly.
