The most notable piece of information or commentary about this little gem seems to be that the group tried to usher in some false pretences to increase their commercial success. 'Recorded in Kansas City on G.M.C. Records,' as the note below the video states, 'in an attempt to bolster sales, producer George Chambers used his brother's San Diego address on the record.' To add, 'The plan didn't work.'
With its cosmic-sounds at the start (that return at the end) you can see why the song received the adjective psychedelic. Funk and soul also make sense but the most interesting for me is the disco appellation. Around 2’30” the song that had until then been a loose soul-inflected groove enacts the exposed percussion style that typifies a disco song, but the rest of the band plays on (albeit more subtly). It’s a fresh-take on the classic disco tic of allowing the drums, or bass take the floor by themselves as the other instruments look on, so to speak.
There’s lots to like about this song that seems barely remembered 40 years on, the clapping beat/the ‘hey!’ the singer's self-assurance and verve and the sweet and simple lyrics.
