last big song ?
well, i'm gonna swim with the majority, here...
first, the template was not set well by your qusetion, ed: did you mean last big hit...if so, it has a heck of alot more to do with the industry ( both radio and recording ) as well as a healthy dose of the key demographic of the recent/present day...that is...young folks...
if you mean last big, recognizable song, well, i'm afraid i'll pull out a chestnut (and agree, offhandedly, with most of the rest ): when i saw macca on the FITD tour, there were old fogeys who only wanted to hear beatles songs (maybe BOTR...Jet) there were also quite a alot of people who wanted to hear anything the guy did...but there were two teenage girls who wanted to hear the new stuff, they cheered for each new song, each of those were big songs for them (and me)
the same would happen today for kids who listen to a wide variety of music, including macca...( and there are some ).
i know of quite a few who would, especially if ticket prices were far more reasonable, have no problem going to see him, and they would be looking for the new stuff just as much as the old....in some cases, some songs - even more.
each individual might view each song as a big song, thus all the passion many feel around here for various songs (yes, house of wax IS a great song: i'd love to see him do that complete cycle of songs) off all these albums
you wake up...sip hot tea...mindless music, radio free. see blue skies and think of sea...how are you doin'
