I recently (March 2002) went through my Peddlers albums and made a selection of my faves, which was exactly enough to fill an 80 minute CD. I could probably recommend any song that's on it, so why "On a clear day?" Because it never failed to cheer me up, I guess, and after 30 years it still hasn't managed to induce the slightest sign of boredom in me, because I just love Roy Phillips's singing, his characteristic smokey, velvety voice, and his fabulously stuttering hammond solo, and because of the lush stringy orchestration and Trevor Morais's typical drumbreaks. The song itself is a blast in itself too, of course, I know of a version from the same period by Cleo Laine that I also really like.
