I really like 'Long, Long, Long' espacially after the 'I've got blisters on my fingers!' ending of Helter Skelter, and it's like a 'Good Night' to me, I fall asleep after like 40 seconds. Definetly in my top 5 Harrison songs.
I think 'Piggies' is fine. Great guitar and quite funny lyrics.
'WMGGW' is fine, too. But a bit boring and too long. I can't see why so many people consider it as the greatest Harrison song. I gues it's just overrated...
