Not quite sure what EMI were thinking about when they out this one out on their budget label.
The opener Living in the Past is not the recognised studio version but a 'live' instrumental and not mentioned as so on the album notes
That said, and you fancy a collection of good tracks from a number of different albums, then this might work for you.
By no means a 'Best of' collection, this does have a selection of great songs...Budapest from Crest of a Knave, Still Loving You tonight from Catfish Rising and Beastie from Broadsword - top that with a live Locomotive Breath and you have some of Tull's best.
Problem is that there is no link in the sleeve notes as to which album each track comes from - which is a bit of a blunder, but at 3.99 its worth a snip!
