Actually it was a #1 hit in Britain. Somehow I missed it back in the day. Garage soul with Satisfaction-plus fuzztone. That singer’s got some pipes. They didn’t write it but they might as well have. The original by Jackie Edwards is an early reggae song and a fine tune, but Spencer and the fellas make it something else again.
This is the blueprint for the kind of tune Hellacopters would cover. Maybe they didn’t cover this one because it would be a cover of a cover. I (and surely the Hellas) would throw a crazy guitar solo in there somewhere, but it’s still mighty fine as is.
