This career overview of Fairport Convention tracks the British band’s progression from folk traditionalists to folk-rock pioneers. The title track was just their second single, but it became an anthem due to its rousing feel and gospel-tinged chorus of massed voices. Their cover of Dylan’s “Percy’s Song” features stirring harmonies, while the guitar/fiddle interplay and Sandy Denny’s yearning vocals on “Who Knows Where the Time Goes?” and “Fotheringay” make them sound like ancient ballads rather than songs of their time.
