Collins arranged and composed many major works and lighter pieces, which include the still-popular Vanity Fair. This work and numerous other miniatures and suites by Collins are to be found on a 2005 CD, featuring John Wilson conducting the BBC Concert Orchestra. Collins also edited the Threnody for a Soldier Killed in Action from sketches left by Michael Heming, a young composer killed in World War II. His Elegy for Edward Elgar has been recorded, including a theme from the third movement of Elgar's third symphony.
