I was so surprised when I saw this combination released. I always wanted all the alternative versions of "Sexual Healing," and I suppose, they're pretty much all here. However, Disc Two in this two disc set claims that all the tracks contained there are previously unreleased tracks, which is very wrong! I purchased the "Alternative Vocal Mix" of Sexual Healing and My Love is Waiting as a 12" release from Old Gold Records Ltd. in London. I've just been looking for other versions, and that's why I ended up purchasing this CD with absolutely no regrets. Check out the "Alternate Instrumental Version" of Sexual Healing, it'll make you melt... instantly.
