For what it's worth Donna Summer is a real legend to me, some of those disco records were amazing.
Darlene Love, well, less so, but she's still had a great career, icluding singing on loads of great Duane Eddy records. Saw her in Hairspray on Broadway in 2005 when I went to see MK, and of course she was Danny Glover's wife in Lethal Weapon.
