Rock drummer David Holland has been convicted of trying to rape a special needs youngster.
Holland has been convicted of attempted rape
Holland was also found guilty of five charges of indecently assaulting the teenager.
The musician, who played with the band Judas Priest in the 1970s and 1980s, was convicted of the charges at Northampton Crown Court on Friday.
Holland, 55, of The Green, Stoke Bruerne, who denied all the charges, was convicted on majority verdicts.
All the offences took place at the drummer's Northamptonshire home between June and December 2002 when he was giving the 17-year-old drumming lessons.
Judge Charles Wide QC said he was very concerned about the risk Holland presented to adolescent boys and remanded him in custody for a pre-sentence report.
"I in particular would be interested in an assessment of the risk Mr Holland poses to adolescent young men," Judge Wide said.
Holland's co-accused, Spiros Laouitaris, 22, of Bourne Crescent, Kings Heath, Northampton, was earlier acquitted of three separate charges of indecently assaulting the same teenager, who is now 18, but who cannot be named for legal reasons.
He was cleared of a fourth indecent assault charge on Thursday on the directions of Judge Wide, who said there had been insufficient evidence.
The jury was told the teenager's parents had organised the lessons to boost their son's self-esteem.
As the relationship between teacher and pupil grew, they had allowed him to stay at Holland's home.
The jury heard the abuse was revealed in a letter written by the teenager to his parents on 14 December, 2002.
Maria Savvides, prosecuting, told the court the boy had managed to stop Mr Holland from raping him but said he had been abused in other ways.
