Paul Sinclair (from Super Deluxe Edition) has written a very thorough review of the 5.1 mix here:
http://www.superdeluxeedition.com/r...surround-sound-mix-of-the-beatles-sgt-pepper/
10 tracks (including "Penny Lane") are labeled as having 'Good' 5.1 mixes
3 tracks are labeled as having 'Very Good' 5.1 mixes
Finally 2 tracks are labeled as having 'Stunning' 5.1 mixes (and one of them is "Strawberry Fields Forever")
In closing:

What is Sinclair's history with reviewing multi-channel titles? I really don't know. Does he have a thorough appreciation for MC? Or, more of a stereo/mono sort of guy?
