OASIS fans who claimed their money back after the band's disrupted Heaton Park gig now face a dilemma.

That's because the refunds are on Bank of Burnage cheques signed by the Gallagher brothers and could well become collectors' items.

Despite featuring the logo of the fictitious bank, the cheques are legal tender and can be cashed normally. But promoters for the gig suggested that some fans may want to keep the distinctive novelty cheques, which bear the signature of Liam and Noel Gallagher, as a memento.

A band spokeswoman said: "People can obviously cash them in. They are quite distinctive so a few people may decide to keep them."

Michael Jackson fans who paid in advance for the singer's UK concerts have been offered their money back or a souvenir ticket as an alternative.

Promoters say the Jackson tickets will become collectors' items featuring special images which give them a 3D moving effect. Oasis face a £1m bill after more than 20,000 fans took up Noel's offer of a refund over their Heaton Park gig.

The band's opening night concert in Manchester on June 4 was marred by technical glitches, with two separate power cuts leading to a 50-minute delay.

Speaking to fans from the stage, Noel vowed a refund to those dissatisfied, saying: "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."

More than 70,000 fans had paid £45 for tickets for the show. But the guitarist later hit out at the large number of 'cheeky' gig goers who took up the offer.

Writing on his blog, he said: "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."

The band were last night starting a three-day stint at Wembley stadium.
