Also in 1998, Batt produced, arranged and conducted the album, "Philharmania" with the Royal Philharmonic and guest singers included Joey Tempest, Roger Daltrey, Marc Almond, Bonnie Tyler, Status Quo, Huey Lewis, Kim Wilde, Justin Hayward and others. Later the same year, Batt relaunched The Wombles pop group, with two hits, "Remember You’re A Womble" (at number 13) and "The Wombling Song" (at number 27). In 2000, he collaborated with Roy Wood for a single which combined new versions of previous Christmas hits by Wizzard and The Wombles, released as "I Wish It Could Be a Wombling Merry Christmas" – UK number 22). In 1997, the year of The Queen and Prince Philip's Golden Wedding Anniversary, he was commissioned by the military to compose a piece, "Royal Gold" for the massed bands of the Coldstream, Welsh, Irish and Grenadier Guards, together with 100 pipers. The piece was performed in the presence of The Queen and Prince Philip at the Royal Tournament in that year. Batt simultaneously dedicated the piece to his own parents, whose Golden Wedding Anniversary happened to be in the same year.
