"It is with great sadness that i have to report that the great guitar player with CARSON has passed away.
Sleepy Greg Lawrie was a unique slide player that made this band what it was. Along with Broderick Smith's unique vocals and the other members, CARSON became a favourite of the 70's.
There big hit "Boogie" is well remembered by anyone that grew up with Australian music of the 70's."
