Noel and Liam Gallagher are in top-secret talks about re-forming Oasis.
The brothers have been approached by promoters willing to pay huge sums for them to play two shows to mark 20 years since their debut album.
And their answer could match the album's title: Definitely Maybe.
The pair could be tempted, despite Noel once saying the band wouldn't re-form "even if all the starving children in the world depended on it".
Talks are said to be fragile but the package on the table may prove irresistible to Liam.
The 40-year-old needs to pay for £500-an-hour (NZ$974) lawyer Fiona Shackleton, who is handling his divorce from Nicole Appleton.
Oasis split four years ago after fighting between the brothers. Since then Liam's new band, Beady Eye, have had only a fraction of the success of Oasis.
If the concerts do go ahead, they are expected to be staged next August at Knebworth.
When Oasis played there in 1996 they sold 330,000 tickets - the fastest-selling in British rock history.
A source said: "If the gigs happened, they would perform Definitely Maybe from start to finish."
Liam and Noel have not been on stage together since a dramatic showdown at a Paris gig in 2009 when Liam reportedly smashed one of Noel's guitars.
Noel, 46, subsequently quit the band saying: "I simply could not go on working with Liam a day longer."
He has since fronted his band High Flying Birds.
But in June, Liam hinted there could be a reunion. He said: 'I'd do it for nowt, but if someone's going to drop a load of f***ing money, I'd do it for that too.'
Both brothers' spokesmen declined to comment.
