The Stone Roses will release their first new music in more than two decades on Thursday night.
The T in the Park headliners have not released new music since the mid-1990s.
A spokeswoman for the band would not give any further details on the single, including how or in what format the single will be released.
And on Thursday they simply tweeted: “THE STONE ROSES WILL RELEASE A NEW SINGLE TONIGHT AT 8PM.”
Colin White, owner of Vinyl Revival record shop in Hilton Street, said a poster had been put up outside his store on Tuesday and excitement had been building.
The 48-year-old, who counts himself among their fans, said: “Roses fans are coming in and saying, ‘Have you heard the news?’ I’ve had lots of people coming in and they were really excited.
“I’m excited but I’m hoping it’s going to be something a bit better than the ordinary.
“I had been told they would be trying out new stuff at the gigs.
“They are geniuses at keeping things quiet.”

Fronted by Ian Brown, the four-piece are often hailed as the inspiration for a generation of bands.
The Stone Roses made a triumphant comeback in 2012, having announced in 2011 that they were reforming after an acrimonious split 15 years earlier.
The reunion was one which many fans thought would never happen after their bitter fall-out.
They had long met rumours of a revival with assurances that the band would not reform.
But they eventually buried the hatchet in 2011, agreeing a series of festival dates and a three-night stint topping the bill at their own mini-festival in Manchester’s Heaton Park.
The show was the band’s first large-scale show in the UK since the group fell apart in 1996.
