A school concert by rock superstar Eric Clapton in Sheffield was a once-in-a-lifetime experience for the staff, pupils and parents, according to the head teacher.
The audience paid £22.50 each to see Clapton
Clapton, 57, swapped the world's greatest concert venues for Tuesday night's event in the school hall at Birkdale School.
His 17-year-old daughter Ruth is a sixth-former at the fee-paying school and the guitar legend agreed to stage the performance to raise money.
Demand was so high for the private concert that names had to be drawn out of a hat for the 790 tickets, which were sold for £22.50 each.
Head teacher Robert Court said Clapton performed some of his classic tracks before taking questions from the audience.
Mr Court said: "Playing such an intimate venue will have been quite a change from the stadiums Mr Clapton is used to.
"His performance was truly a once-in-a-lifetime experience for all those involved and we are very grateful to him for giving up his time in this way."
He said the concert raised more than £10,000 which will be split between the Friends of Birkdale School and a drug rehabilitation centre in Antigua supported by Clapton.
Mr Court said the Friends would use the money to buy musical instruments - particularly starter instruments such as small violins - and IT equipment.
