I know Chris Solberg, so I decided to ask him. Dave Margen was the bass player. Chris Solberg played guitar and some keys while Alan Pasqua was the main keyboardist. Graham Lear on drums, Raul Rekow and Armando Peraza on percussion, and Alex Ligertwood on lead vocals.
Solberg wrote/co-wrote (7) songs on that album, including 'All I Ever Wanted' and 'You Know That I Love You.' He did play with Eddie Money, and is a fantastic bassist and guitarist.
Dave Margen's recorded history is mainly with Santana. Moon Flower, Inner Secrets, Oneness: Silver Dreams Golden Realities, Swing of Delight, Bebop!, Shango and Havana Moon, Blues for Salvador, and Viva! Santana. He also recorded a Joe Walsh album and Greg Rollie solo album.
I don't know anything about Dave Margen. He's a great player- I'd love to find out more about him. There are a limited number of posts on talkbass.com about him.
What happened to David Margen???
mentions a live recording on Wolfgang's vault.
