Lonnie Donegan combined an American folk song with a stripped-down, back-porch jazz dance rhythm to create what eventually became known as skiffle in Britain when “Rock Island Line” was released and took the country by storm in 1954. Donegan went on to turn the same trick with “Cumberland Gap,” “Jack O’Diamonds,” “Tom Dooley,” and other folk tunes through the 1950s up until 1962 -- his commercial career ended when skiffle’s nearest and dearest cousin, rock & roll, appeared on the scene, a music Donegan himself supplied a template for with his amped-up versions of old folk and blues tunes. All of the above sides are included in this concise 18-track survey of Donegan's important moment in the sun.
