This compilation includes the best of their music from mid-1969 to 1972. This period started with Saved by the bell (a Robin Gibb solo) and Don't forget to remember (perhaps my favorite Bee Gees song), both of which reached number two on the UK charts. They had little success for some time after that. In 1970, I O I O scraped into the top fifty, but Lonely days did better, making the top forty. In 1971, they didn't enter the UK charts at all. 1972 was better with My world making the top twenty and Run to me making the top ten. They had never really established themselves in America with their sixties pop-folk music and the songs from this collection didn't change that.
So this album may be seen by some as the best of a bad period in the careers of the Bee Gees. In fact, there are many good songs in this collection. I particularly like Melody fair and Morning of my life. Are the songs really weaker than those on the earlier volume, or is it just that people were tired of the style and wanted something different from the Bee Gees? It is probably a bit of both.
If you enjoy the earlier Best of Bee Gees, you are likely to also enjoy this - but not quite as much.
