Like the not-so-simpletons he played onscreen, the singing actor born André Robert Raimbourg in 1917 specialised in comic songs whose naïveté disguised their sophistication. Among his 300 light-hearted numbers, often delivered with a knowing chuckle or moist-eyed sentiment, are charming takeoffs on garret-living bohemians, would-be poets, flat-footed gendarmes and wife-stealing Yankee soldiers.
