I was lucky enough to catch Chicago (with The Beach Boys at the Capital Centre [R.I.P.] on June 25, 1975) while Terry Kath (also, R.I.P.) was still alive. The group had released Chicago VIII earlier in the year (March) and had this album waiting on the back burner for the end of the year (November - which might explain why Old Days was left off it). While some people might bellyache about this album using only the single version of many of these songs (as well as it maybe not including a personal favorite), I think that this is the tightest collection of Chicago's "hits" available at any time in their long history. It may not contain all of them but it has all the important ones up to the point of IX's release. There is no padding here (like many of today's "greatest hits" packages that get foisted upon us too early [or too often] in a group's career) and it is a great representation of the original group (with the late addition of Laudir de Oliveira) before it got diluted (for various reasons) over the years. I've owned this album on vinyl, 8 track, cassette, and CD. That alone shows it's continued appeal to me. It's a shame that it has been deleted from the current Chicago catalog. I can only hope that one day, someone has the sense, resources, and balls to release an expanded version of IX that would contain full versions of each song, include a more informative booklet, and add Old Days (where it belongs). Until then, I'll hang on to my cassette and CD versions and hunt down used copies for my friends and family who weren't lucky enough to score one the first time around. A solid V stars for Chicago IX.
