Music on Vinyl released a pretty good sounding double record package called "The Collection" last year. It includes all the hits plus some deep album tracks and obviously songs that the Singles 69-73 doesn't have.
Carpenters
Just finished watching a PBS show/fundraiser about the Carpenters, and it made me realize even more than I had prior just how fantastic (I think) Karen was as a singer. My regret, and its a small one I suppose, is that her brother has taken it upon himself to "remix" most/all of the music they made together; I prefer to hear the music/songs as I recall them when they were new/fresh. Truly a remarkable singer. To me and my tastes.
