You know, I think I like Ozzy more with Black Sabbath than his solo stuff. His solo stuff is good, but whenever I listen to it I think I give more consideration to his guitarists than him.
Case in point: “Mr. Crowley”
I was always a Randy fan (vs. Eddie Van Halen). And I think his classical influences show strongly on “Mr. Crowley”.
And one thing I always appreciated about Zakk was while he was still Zakk, still had his playing style, he honored Randy’s composition, playing the song as it should be.
I say this because, as I write this, I have fresh in my mind a cover band I heard at a small festival. They were actually pretty good, but then they played Ted Nugent’s “Strangehold” and butchered it. Solos aren’t just a time to wank off; sometimes they are, but sometimes the solo line is very much a composed piece that makes the song what it is and you just can’t deviate from it. “Strangehold” is one such song. “Mr Crowley” is another, especially on the outro, and while Zakk throws in his signature vibrato, it’s still Randy’s composition.
Stuff From Hsoi 
I think my favorite Ozzy song is ‘Over The Mountain’. When I was a kid my first for-real concert was Ozzy. The show was delayed due the the death of Randy literally days before the show I had tickets for at the Capitol Center in Largo MD.
Once the tour was back on and the rescheduled show came to town I was still blown away. Brad Gillis (lead axe swinger for Night Ranger) filled in for Randy. He did an awesome job.
Oh man… the Cap Center. I saw many a show there growing up. 🙂 Which then makes me wonder, have you ever seen “Heavy Metal Parking Lot”?

If not, you must. 🙂
Brad Gillis is under appreciated and his contribution to Ozzy’s history is often overlooked.
