Morrissey has apologised for postponing more shows on his US tour.

The former The Smiths frontman has cancelled shows in Denver, Salt Lake City and San Francisco as he continues his treatment for a bleeding ulcer and Barrett’s esophagus. This follows previous cancellations earlier this month (February).

Writing on fan site True To You, the singer issued an apology to fans for postponing the shows and said that he is at “the mercy of biological chance”, before asking fans for their “liberal tolerance”.

He wrote: “I apologize to an almost annoying degree for any trouble I’ve caused to anyone by way of travel plans and dog-sitters and ticket-outlay and re-molded hairstyles.

“My ulcer is now under reins, even if neither asleep nor dead, but the continued cause for concern is a slightly embarrassing absence of blood – most of which the bleeding ulcer relieved me of. Anemia sets its own terms with quite obvious biological conclusions, and I have spent these last weeks under expert medical care in Los Angeles with an almost erotic dependency on various IV drips.”

The singer said that his goal was to make the gig in San Diego on February 27. “I gorge myself on thanks for the many and varied messages of support that I’ve received over these recent four weeks. They have yanked me out of prolonged mood dips and cured a crisis of spirits,” he added.

These postponed gigs are already part of dates rescheduled from October last year, when Morrissey stopped mid-tour to return to the UK to be with his ill mother. She has since recovered.

Meanwhile, Parlophone Records will put out a limited edition seven-inch picture disc of Morrissey’s 1989 single ‘The Last Of The Famous International Playboys’ and a remastered version of his second solo album, 1991’s ‘Kill Uncle’ on April 8.
