I personally think I prefer Tony Martin, honestly. Interesting history though.
I've got the multi-discs of the Dehumanizer demos (the ones from Cozy Powell's collection are solid, and there's a second set that has Ronnie on them and there's an interesting intro to Letters From Earth that didn't make the album and at least like 2 songs that didn't make the album that were solid). And I've also got the rough demos from Forbidden, which IMO much like the Born Again rough mixes were better than how the album itself turned out somehow.
