Not really, they just release the odd cover now and then. A millionaire's hobby (the rhythm guitarist/band leader, one of the wealthiest Australians, Richard Branson type entrepreneur). But as a DP fan, bands backed by wealthy investors are nothing to complain about, Purple was "manufactured" from the start.
Don't you remember Utrecht, Holländer? We saw the Dead Daisies there opening for Coverdale's Weißschlange - at that time Corabi and Mendoza were still singing und playing bass, respectively, Glenn took both their places! The ole multi-purpose tool from Birmingham.
Which is ironic, as both are (or at least were!) admirers of Glenn's singing and bass playing. Mendoza's solo albums sound like souped-up Hughes efforts und Corabi cites "Stormbringer" as one of his alltime favorite albums.
Anyway, you liked the Daisies back then! They had the GnR keyboarder and I believe Bumblefoot as lead guitarist with them at the time.
For me, the Dead Daisies project is of great interest because of the combination of people. Aldrich has toured with Hughes before, they were a wonderful match. Best one since Hughes played with Thrall or even Bolin/Blackmore, that good. And Dean Castronovo - when not busy with domestic violence at home, allegedly - banged the sticks for Journey (and has a singing voice much like Steve Perry).
Of course, the Revolution Saints are an Italian recipe of Frontiers Records, elephants' graveyard for all things AOR and home of Night Ranger (the bassist in the vid is Jack Blades, one of my favorite Republicans), Doug Aldrich solo stuff, modern day Journey, Glenn Hughes, Dead Daisies etc.
PS: I do like the, how shall I put this ... tasteful innuendo of that Revolution Saints vid, for a moment I thought she was gonna pee in that coffee mug which would have greatly enhanced overall dramatic effect ... aw shucks, no such luck.
