I'm gonna give a pitch for Diver Down being unfairly or excessively maligned. Yes, it had a bunch of covers, but some of those covers were really well done, and the originals were excellent.
Where Have All the Good Times Gone -- Kinks cover. I don't know the original. The VH version is excellent.
Hang 'Em High -- Original. Completely kick ass song. As far as I'm concerned, it holds its own against any other DLR-era song other than Unchained.
Cathedral -- Original. This is an Eddie solo pieced in which he makes his guitar sound a bit like a church organ. It's fine for what it is.
Secrets -- Original. Good but not great.
Intruder -- Original. Instrumental that functions as a lead into to the next song. In that context, it is excellent.
(Oh) Pretty Woman -- Roy Orbison cover. Umpteen times better than the original. Great cover.
Dancing in the Street -- Martha and the Vandellas cover. Again, much better than the original (as well as the Bowie/Jagger version).
Little Guitars -- Original. This is actually split into two tracks on the album: Little Guitars (Intro), which is a 42 second classical guitar piece by Eddie, and the song proper. Good song.
Big Bad Bill (Is Sweet William Now) -- Cover, but I'm not sure who the original artist was. This is where the album kind of came off the rails. It's sort of a bluegrass/dixieland/barbershop quartet song. This quote from Eddie sums it up: "It was Dave's idea to do 'Big Bad Bill.' He bought himself one of those Sanyo Walkman-type things with the FM-AM radio, and you can record off the radio if you like something you hear. He was up in his bedroom at his father's house and he found that if he stood in a certain spot and pointed his antenna a certain way, he picked up this weird radio station in Louisville, Kentucky. He recorded 'Big Bad Bill' and played it to us, and we started laughing ourselves silly and going, 'That is bad! Let's do it!' Dave suggested, 'Hey, we can get your old man to play the clarinet.' We said, 'sure.'"
The Full Bug -- Original. A good chunk of this song is pretty cool, but it opens with this old time ZZ Top thing (I think it's similar to La Grange, but I'm not sure about that), which returns after the guitar solo. The rest of the song is good.
Happy Trails -- Roy Rogers/Dale Evans cover. The band did this in the traditional style, and it's fine as far as it goes, but it brings the album to a dud of a conclusion.
In addition to what's noted above, the other well-deserved criticism is that the album is only 31:04. If it had been 10 minutes longer, then wasting time with stuff like Big Bad Bill and Happy Trails might have met with a bit less criticism.
