This is the third edition of the man's Greatest Hits, from what I can tell. The first in 1975 with 10 tracks (vinyl-only), the second in 1995 with five additional tracks (CD-only), and this in 2007 with six additional tracks to the 15 in 1995. Here are the six:
"Take Me to the River"
"Keep Me Cryin'"
"Oh Me, Oh My (Dreams in My Arms)"
"Back Up Train" - from Back Up Train
"I Can't Stop" - from I Can't Stop
"Perfect to Me"- from Everything's OK
The last three are not on the two-disc The Absolute Best. I have noted above where those three are taken from. I have the latter two. I am evaluating the first album, Back Up Train, but will obviously not upgrade to this for that track alone, no matter where I come out on the album.
