Bee Gees

I have noticed their discography ends at SNF. The original lineup basically ended in 2003 after Maurice died.
Also you don't have "Main Course" from 1975 which was their first "disco" album.

I've started to work on Bee Gees again (having done the original entries, broke off to do something else).

For any particular album, there is sometimes difficulty establishing exactly who was in the Bee Gees and who was only guesting, so care needs to be taken.
