The songs in "All you need is cash" showed that Neil Innes is the Master Crafter of the Beatles pastiche, and I would give that CD five stars. I found the "Archaeology" CD a tad disappointing, certainly the first half. But, the second half really gets into stride, with some of the expected subtle touches and excellent writing - Innes is a good song-smith In His Own Write. The references pile on thick and fast in "Shangri-La", which might also be called "Hey Jude! - all you need is a day in the life of Mr Kite in Penny Lane", complete with quotes from Prokofiev! Very clever; even the exasperatingly long run-out is there. The playing is up to the same high standard as "Cash".
So, while "Cash" gets five stars, I'll be honest and give "Archaeology" a well-deserved four.
