Like your review, although I think Temporary Secretary might just be warming on me now, nearly 30 years after I bought it! Think I must have bought this in about 1983, probably the first McCartney album I bought (or possibly Tug of War, can't remember now!). As you say, with the passing of years the album's generally grown on me (maybe it's our age? nothing wrong with being 41!). Interesting comparison with the Fireman albums too, I hadn't thought of that connection but it's a good point. As for the sleevenotes, you really need the deluxe edition for that, it's well worth it for the photos and history of the album although it doesn't give much info away on track details or recording dates unfortunately as none of it was logged anywhere by Paul - he simply made the album up as he went along, in his home studios in Sussex or Scotland. All the songs just show a recording date in the book of summer 1979 with mixing dates in Abbey Road being a bit more specific in September or October 1979, apart from Blue Sway which was overdubbed in 1986 for the long running Cold Cuts project.
Definitely looking forward to the reissues of Back To The Egg and Tug Of War - two of his best albums. I hope the Back to the Egg TV special is on a DVD with all the promos from the album. I remember that being shown on TV in the pre-video days and being forced to go to school that day so never got to see it!! Aaarghh!
