Very sad news. Not just a great performing group, but one of the best song writing teams ever. So many great songs written and performed over 40 years, and so many of them covered by other great artists that became hits.
What ever you may feel about disco, Saturday Night Fever is one of the greatest LPs ever. Full of great songs which were all written by the Bee Gees, and performed by them and other talented artists, to create one of the biggest selling LPs ever, and not forgetting the singles from it. If I was forced to choose my favourite from amongst the many I think it would probably be Massachusetts.. fantastic.
