Spanish singer-songwriter Joaquin Sabina announced the postponement of tours he had scheduled for May in the United States and for June in Mexico because of an illness due to "acute diverticulitis" with risk of complications.

His promoter in Mexico, ErreEle Producciones, said in a communique that this Thursday "during a doctor's appointment made for a checkup because he had been feeling ill for several days previously," the artist was diagnosed as suffering from "acute diverticulitis with risk of later complications in his current state."

To complete Sabina's treatment, the firm said, "he has been prescribed complete rest at home for six weeks."

Following his diagnosis, doctors asked the singer-songwriter not to take any "airplane flights because of the risks involved," the promoter said.

As a result the Spanish singer-songwriter was forced to suspend his first-ever appearances in the United States, part of a tour dubbed "El Penultimo Tren" (The Second-to-last Train), his spokesperson in New York said.

Sabina had also scheduled concerts at the National Auditorium in the Mexican capital for June 11-12-14, which have now been rescheduled for Nov. 4-5-7, ErreEle Producciones said.

The artist is "deeply sorry" about postponing the concerts and "the annoyance it will mean to all who have purchased tickets (for the National Auditorium)," the company said.

In April the singer-songwriter said in a statement to Efe that it was "fear, nothing but fear" that had kept him from performing in the United States.

"The truth is I'm scared to death. I have this mythical image of New York, the great Babel where the greatest artists in history have appeared. It's a little intimidating, even more so for a kid from the provinces like me," the singer-songwriter said at the time.

Sabina also spoke of other reasons such as his many bookings in Latin America, a continent with which he admits to being "hopelessly in love."
