Iron Maiden and UK brewers Robinson's will launch of the band's Trooper beer in select Robinson's pubs on the evening of May 9.
A recent report in The Sun says the product is experiencing record sales in advance of its official launch, with Robinsons is having to work a six-day week to keep up with demand.

Over a quarter of a million pints have been pre-sold in the UK alone, and more than 100 countries have applied to stock Trooper beer.

The company is brewing three batches a day for the first time in their 175-year history. "We haven't spent a single penny on advertising," said David Bremner of Robinsons. "This is history in the making for brewing."
