Yeah, love the 'light and shade' contrast approach in that song. Listening to it right now. JPJ shows why he's IMHO rock's greatest bassist (also on the 'Lemon Song').
'Ramble On' is another of the more 'mellow' tunes off that album that I love listening to - and even the Tolkien nerds can get something out of it!
