The early success of the Beatles spawned a slew of nice boy popsters on the foggy side of the pond, and “David and Jonathan” (actually Rogers Cook and Greenaway, writing their own songs but performing pseudonymously from 1965-68) were so especially nice that George Martin himself produced their sides and let them have a crack at “Michelle,” a top 20 hit in the US. In time, the duo would reclaim their names and become important producer-songwriters (“You’ve Got Your Troubles,” “I’d Like To Teach The World To Sing”), but first they dropped themselves into the gumball machine, with this turn offering idealistic folkster crooning over harpsichord (“Lovers of the World Unite”), the next nonsense big band bubblepop silliness (“Gilly Gilly Ossenfeffer Katzennellenbogen By The Sea”), and then anxious Beatle-penned melodrama (“She’s Leaving Home”). Dig lush production, Chad, Jeremy, Peter, Gordon and the Freddie? Then this, luv, is for you.
