The Elastik Band's "Spazz" is the kind of single so strange and uncommercial that it boggles the mind as to how it managed to get released on a big label (Atco). Even by the standards of late 1967, when this came out, it was politically incorrect to the max, its lyrics viciously taunting a spastic, its standard blues-rock-garage verses bracketed by cheesy bursts of quasi-Oriental melodies. Could anyone have been surprised when it failed to make the charts? From the San Francisco suburb of Belmont
