Oasis could be faced with a bill approaching almost £1m after over 20,000 fans took up Noel Gallagher's offer of a Heaton Park refund.
The bands opening night gig in Manchester on June 4th was marred by technical glitches.
Fans had paid £45 for tickets for the show, and power was cut on 2 separate occasions.
Noel said: "Thank you very very much, this is a free gig - let's have it... Anybody who has kept their ticket will get a full refund."
Words which may have backfired after the unprecedented size of the response. Oasis fans have been making their request for a refund through the bands website oasisinet.com.
On his official blog, Noel responded with: "It seems that around 20,000 of you have asked for a refund from that night at Heaton Park. 20,000! So you were genuinely disappointed?"
"I don't recall seeing a 20,000 gap in the crowd. Tsk... some people."
Oasis perform Slane Castle in Ireland tonight and return to the UK next month for shows in Coventry and London.
