The reason is problems with the US visa. Cat Stevens writes that he applied several months ago but that he has not received a response and therefore will not have time to get together a tour in the US and Canada.
"I'm really upset!", he writes.
The 77-year-old singer has been on tour to promote his new autobiography. The tour is described as a mix of concert and author talk.
Cat Stevens says that he may carry out the tour at a later date, if his visa is approved. According to AP, several artists have had similar problems, after the processing times - and fees - for US visas have increased.
