I was never a big fan of the song "She's Leaving Home." Like the proverbial dumb blonde, it's pretty enough, but far too silly to take seriously (which sadly applies to many of Paul McCartney's later songs--and, it may be argued, his earlier ones--as well).
Suffice it to say, I've always considered it to be Sgt. Pepper's weakest link.
But now, I've been forced to reconsider that opinion. Although I still dislike the song intensely, this instrumental version has opened my ears to the absolute gorgeousness of the track. Interestingly, the genius behind this magnificent arrangement is not George Martin, but Mike Leander, the only arranger other than Martin to work with the group (Phil Spector doesn't count IMHO since he was basically hired as a clean-up crew, not an arranger).
Also, I guess I knew it at one time, but I had forgotten that SLH is one of the few tracks in the Beatle canon on which no Beatle plays an instrument.

I actually think SLH is a better song than he does, but that's pretty darned beautiful any way you slice it. Incidentally, if memory serves Mike Leander also arranged for the Stones, most famously the string quartet on "As Tears Go By."
