Right after Schon, Castronovo and Jensen left Hardline, all 3 of them toured with Paul Rodgers for his Muddy Water Blues album.
So, Neal and Deen have worked with Todd Jensen a lot.
I may be wrong about this? But I think that I remember having heard back in 1992 or or so that Castronovo may have been in a band with Jensen back in the 80s?
