Back at #40 we had really obscure Temps -- "Happy People." I slept from 35 through 21, unfortunately...
Sadly, you missed Love Unltd's "I Belong To You", Joni's "Big Yellow Taxi (Live)", Mr Valli's "My Eyes Adored You (But My Nose Abhorred You)", Jim Stafford's "Your Bulldog Drinks Champagne" (which sounds like it would've made a great follow-up to "The No-No Song" for Ringo), and a long-forgotten Billy Preston instrumental, "Struttin'". I meant to mention this morning what a treat George's "Ding Dong, Ding Dong" was -- rock stations used to play it every New Years, but it has completely faded into obscurity.
And Casey remarked that the nucleus of Styx started out as The Trade Winds of "NY's a Lonely Town" fame but Whitburn's bios of both acts make no mention of it. BTW, we just missed out on hearing ONJ 3 weeks in a row: "Have You Never Been Mellow" was just outside the Top 40.
