Nice comments here from Maurice
The Bee Gees toured with their band, formed in 1975 and which consisted of Dennis Bryon on drums, Blue Weaver on various keyboards, and Alan Kendall on lead guitar.
This band was more than just a group of musicians playing together. As Maurice once said: “They’re part of the family. Having a band that knows how we play and sing and write has really been one of the keys to our sound.”
