Yes, the three tracks you mention are definitely new/recent vocal recordings. They're not bad per se, but you can clearly hear a huge difference compared to the old recordings that sound a lot better. Not sure why he did that, but it does take away from the overall experience. What I find weird is the acoustic version of True Blue Love; why wasn't there an original vocal recording? Or why not just take the vocal take from the electric version? I love that song, so it would have been nice to have him in his prime singing this. The other two tracks with his current voice are not that great to begin with, so I would have left them out. But I assume they wanted to release a full album instead of just seven tracks.
