Thin Lizzy.
Phil Lynott, the lead singer, had a rather pathetic life. His mother was ... let’s just say she had low morals ... and had three children by three different men. Two were given up for adoption. Phil was raised by his grandmother if I recall correctly. The mother now makes money talking up her dead son, the one she never raised. Disgusting.
Phil Lynott was great, he did a solo album that featured Mark Knopfler on guitar. Sad he couldn’t beat his demons.
