Mystery surrounds country star Merle Haggard's last-minute decision not to open up for the Rolling Stones in Dallas, Texas last night (29NOV05).

The rugged singer pulled out of the show earlier in the day, prompting promoters to call on DELBERT McCLINTON to take his place.

Haggard's handlers are still scratching their heads about his decision, insisting there seems to be nothing wrong with the singer/songwriter's health - the usual reason given for late concert cancellations.
