When I heard that Matt was to be replaced by Jim on this tour, I must admit to being a bit apprehensive, but I needn't have been, because in the main Jim has done a magnificent job and is probably more versatile for the songs on this tour than Matt would have been - with one or two exceptions and PTTE is one of them, probably due to a different arrangement which excluded piano. I agree with LE - Matt is missed on this song!
I have just listened to PTTE from Cordoba 2010 and it was glaringly obvious to me that the piano is missing in the 2013 version! There is a particular part of the song where Matt plays about four notes, just after Mark sings "clouds are lined with golden thread" - for me that was a really memorable and essential part of the song that is now missing, although played on the guitar.
In 2010, at the end when Mark stops playing and waves to the crowd, the band continue play on and it feels like it is the end of some really epic extravaganza and I don't get this feeling with 2013 versions.
