Good call, Leese. Any album with Nobody`s Fault but Mine, Achilles Last Stand, Tea For One and For Your Life on must be right up there. In fact, you`ve convinced me - Presence is my new favourite Zep album !! Oh, wait a minute....I`ve just spotted Physical Graffiti in my collection......oh bugger, there`s Led Zep II next to it.....and III......and IV......
This isn`t fair, the only harder question to answer would be "What`s your favourite Led Zep song?"
