Downton Abbey The Ultimate Collection features all the musical highlights from the entire Downton Abbey legacy. Music from all the series, 1 to 6, is packed into 2CDs with 36 tracks. With the final episode of the hugely popular hit TV show having aired this month and with only the Christmas Special yet to air, the Ultimate Collection will be the essential fan accompaniment to the DVD box set this Christmas. The collection was composed by BAFTA and Ivor Novello Award nominee John Lunn, who also features as pianist on the collection. Other credits include vocalists Eurielle and Mary-Jess Leaverland.
