Philip Lynott (vocals & bass guitar) was one of the founding members and frontman of the group. He passed away in 1986.
During the whole Lizzy existence, they had several guitar players: Eric Bell, Scott Gorham, Brian Robertson, Gary Moore, John Sykes, Snowy White, John Cann, Andy Gee & Midge Ure.
Drummer Mark Nauseef replaced Brian Downey on a few gigs.
Keyboard players were Eric Wrixton (only first recordings of Lizzy) and Darren Wharton (from Renegade till the end).
The most famous and most known line-up was during the '74 - '78 period with Scott Gorham and Brian Robertson on lead guitar.
Currently John Sykes & Scott Gorham are touring with their own band under the name of Thin Lizzy, but this is not always appreciated by the old fans. No Lizzy without Philip...
