Kitchen worker Paul Mulvey's Downing Street serenade to Tony Blair fell on deaf ears - the Prime Minister was spending the weekend at his country retreat of Chequers.

Mr Mulvey, 48, of Vicarage Road, south Oxford, travelled to No 10 on Saturday to deliver a CD of his song, the Railtrack Gravy Gravel Train.

The kitchen porter at Christ Church penned the number in opposition to Railtrack's ballast dump near his home.

Mr Mulvey dressed as a Celtic bard and played his dulcimer, a harp-like instrument, outside No 10.

But the only applause he received after his song was from the policeman standing guard outside.

Paul's wife Maggie Mulvey, 52, said: "Paul was reasonably pleased.

"It went smoothly and the police were nice, but there was no Tony Blair and no press."

Mr Mulvey said he wanted Tony Blair to tighten the law to force Railtrack to get planning permission for the ballast stockpile at Hinksey sidings on green belt land.

Residents in south Oxford claim the ballast, which is used to support Rail lines, will create intolerable noise levels and dust close to homes, a nursery school and a health centre.
