I think because of the massive amount of attention that is given to this album's so called "historical significance" that sometimes not enough attention is given to the music itself. I hope to correct that imbalance with this review which focuses entirely on the album's 13 tracks.
"Sgt. Pepper's Lonely Hearts Club Band" - This is a brilliant way to start the album and it really sets the mood for the entire thing. The "concept" of the album is really quite loose, without this song there is no concept album! One thing I really dig about this song is the crazy horns section. Can you imagine many "rock bands" of today having the imagination to include something like that in their song?
"With a Little Help from my Friends" - I know there are quite a few people who think that Joe Cocker really did the definitive version of this song, but I'm definitely not one of those people. I like Cocker's version, but the original contains the real magic to my ears.
"Lucy in the Sky with Diamonds" - Now that the original mono version is available easily (with the release of The Beatles in Mono Box Set) it's great to be able to hear what this album sounds like in mono (how it was "meant to be heard" originally.) And the heavy vocal effects on this song is probably one of the more interesting things about the mono mixes for me.
"Getting Better" - This song so perfectly encapsulates the sound of this album and what it's all about to me.
"Fixing a Hole" - I love this kind of more subtle psychedelia. And yes, this is a very psychedelic song. And how about those lyrics? Anyone who doesn't think McCartney could write lyrics should pay close attention to these.
"She's Leaving Home" - Another great reason to get The Beatles in Mono Box Set. This song sounds faster and higher (by a semitone) in the mono version. It's a treat to hear!
"Being for the Benefit of Mr. Kite" - I think my favorite part of this song is the cut up tape section where it sounds like sort of insane random carnival music.
"Within You Without You" - I know a lot of people just can't get down with this kind of music but I certainly can. It's a really tripped out journey into the center of your own mind or is that your own heart? Or perhaps it's India!
"When I'm 64" - Some people don't seem to get how "tongue in cheek" this song is. McCartney loved to mess around with different musical styles in this way. In fact I think Ween sort of ripped off their whole shtick from Paul McCartney. Listen to McCartney's "fruity" songs (as George Harrison called them sometimes) from the perspective of Ween doing them and I think maybe they'll click.
"Lovely Rita" - I have to admit that tracks #10 and #11 are probably my least favorites on the album. But considering I quite like both of those tracks, that says a lot about how much I love this album.
"Good Morning Good Morning" - My least favorite song on the album. Yet I still think it's pretty great at times and it has some very interesting elements. I think that says a lot about how much I love this album.
"Sgt. Pepper's (Reprise)" - Rocks harder than the first version. I love how it ties the album together and it's brilliant how this closing version is "looser" just like a band may be looser at the end of a real show. And that's what the concept of this album was all about after all. The idea was that this album would "go on tour" rather than the band themselves.
"A Day in the Life" - In my opinion this is the best song ever written. An absolutely epic way to end the album.
