Just picked up my copy of the 30th Anniversary Edition of Billy Joel's The Stranger at Best Buy. The Anniversary Edition comes with "The brilliantly remastered original album" (actually remastered in 2001, but what the heck) a 1977 concert previously unreleased, and a dvd of The BBC's Old rey Whistle Stop from 1978 including 2 songs that never aired. And because it was Best Buy, another 5 song cd of another 1977 show.
You know I already have the original pressing of the CD, and I even have the 2001 remaster. But I still plunked down my $30 to get it again to get the new stuff that was added. This is a lesson Styx should take note of. WIth the 35th Anniversary of the classis albums coming up, they certainly could get the die hards to repurchase the catalog if they added just the extras like Billy Joel has done.
