 Ironically, the roots of the British Invasion were in American folk, specifically a variant known as skiffle as popularized by Lonnie Donegan; however, most of the British Invasion bands had been extensively influenced by rock and roll by the time their music had reached the United States and bore little resemblance to its folk origins.After Bob Dylan began to record with a rocking rhythm section and electric instruments in 1965 (see "Electric Dylan controversy"), many other still-young folk artists followed suit.Meanwhile, bands like The Lovin' Spoonful and the Byrds, whose individual members often had a background in the folk-revival coffee-house scene, were getting recording contracts with folk-tinged music played with a rock-band line-up.
