In 1967, the Bee Gees announced their arrival on the British music scene with "Bee Gees 1st", an album that ranks among the best work produced that year. So why is it rarely mentioned in the same breath as the Beatles' "Sgt Pepper" and other iconic releases of the time? I'm joined by Australia-based youth culture and popular music historian Dr Christine Feldman-Barrett to discuss what makes "Bee Gees 1st" such an important album – and how the Gibb brothers' emigration from the UK to Australia and back again influenced their music so strongly.
