Mungo Jerry’s shot at the mutant blues suffers from its proximity to Hendrix on the one side and T Rex on the other. Those sci-fi and glitter visions make “Baby Jump” sound like a smirk, not a strut, a cartoon growl that’s too broad to be funny (despite its clever-clogs lyrics). The band try hard to sound like wild men – but only the piano man, making his instrument into a toy laser pistol, manages it. Worst mistake though is the horribly unnecessary false ending, a perfect case study in how to kill a song’s energy and make it outstay its welcome. .
