FORT EDWARD, N.Y. – Former Phish lead singer Trey Anastasio spent two days in an upstate New York jail last week for missing a counseling session required after he pleaded guilty to a drug charge in April, according to a Washington County prosecutor.

Anastasio, 43, was ordered to participate in the county court’s treatment program when he pleaded guilty to possessing painkillers without a prescription during a traffic stop in December 2006.

The program requires weekly court appearances for 12 to 15 months, community service and drug testing.

Assistant District Attorney Tony Jordan told the Glens Falls Post-Star that Anastasio, who lives in Richmond, Vt., missed one counseling session and the violation did not involve a drug test. He said Anastasio hasn’t missed any drug tests and has passed them all since pleading to a felony charge of fifth-degree criminal possession of a controlled substance.

Sheriff Roger Leclaire said the musician’s two days in jail were uneventful and he spent them in the general population.
