I've always loved "I'm In A Different World" from the first time I heard it on the "Yesterday's Dreams" LP. At the time, I had no idea that it would be HDH's last outing with the Four Tops AND with Motown. Strangely, I don't recall the single getting any airplay on our local AM radio station which had always promoted Motown fairly heavily throughout Motown's classic era. It's still beyond me how Motown let a surefire hit like "Your Love Is Wonderful" slip through their fingers yet felt compelled to include an annoying track like "The Sweetheart Tree" on the "Yesterday's Dreams" album.
