Macroom’s 'Mountain Dew' was Ireland's first rock festival

It seems like old hat now, a music festival, but when the first major gathering of music stars arrived to perform in Macroom, County Cork, it changed for ever how music would be enjoyed countrywide.
It was a very big deal. Major concert promoters had dismissed the idea of an outdoor one, but a town with a population of 3,000 was fearless, and the result was an unprecedented 20,000 music fans arriving to listen to their music heroes. Forty years ago they made history.
