A truly odd popular music ensemble for 1970s Britain, Lieutenant Pigeon enjoyed a fairly long and successful recording career with their offbeat, mostly instrumental music. Not exactly easy to categorize as rock, it's nonetheless hard to know what else to call their mix of martial percussion, century-old-sounding parlor music, and weird insertions of fifes, rickety pianos, and half-buried miscellaneous vocal growls. That their debut single, 1972's "Mouldy Old Dough," made it all the way to number one in the U.K. is a testament to the British tolerance, and indeed encouragement, of eccentricity that could be cultivated nowhere else. The group released three albums in the early '70s and continued making music of a sort (jingles, commercials, and the occasional song) in the decades that followed.
