I am by no means an expert on Bachman-Turner Overdrive. I am just a casual listener to their music; I know their hits but little more. I am not qualified to analyze this two-CD set as others have done on other websites. Let me just say I got this set for a very good price. All of the hits I can remember from BTO are on here. I am unaware of any omissions that should be included. I cannot judge studio versions versus live versions of certain songs. I enjoyed hearing again BTO's hits and I also enjoyed hearing songs with which I was unfamiliar before receiving this set. I am glad I made this purchase.
