Was HE ever released as a maxi-single? wikipedia is listing it as one. I know that dj's would submit track[[s) to Billboard for the dance charts. And sometimes they would only list the released 7" single or sometimes it would be listed with multiple tracks from the lp or even the whole lp.

For instance, Let Yourself Go, You're My Driving Wheel and Love I Never Knew were all listed on Billboard's dance tracks and charted at #5. But there was no "medley" of the songs and Love was only released in Europe.

I'm not aware of any extended singles on the Sups until the hits medley in 79.
