Led Zep rocks no matter which side of the spiritual ledger they are on.
Take a wild guess.
Although it would be easy to guess that they aren't on the side of the Lord, they may have had some spiritual awakenings in more recent times. I will say I'm not going to be throwing any stones for the things they did in their youth. Even the most strong willed Christian would be hard pressed to stay true while in the biggest (and best) rock band on the 70's.
