Hobbs joined the
D'Oyly Carte Opera Company in 1914, taking over many of the roles played by the departing
Sydney Granville, including Colonel Calverley in
Patience, Lord Mountararat in
Iolanthe, Arac in
Princess Ida, Pish-Tush in
The Mikado,
Richard Cholmondeley in
The Yeomen of the Guard and Luiz in
The Gondoliers. He soon added to his repertory the parts of Counsel to the Plaintiff in
Trial by Jury, the Boatswain in
H.M.S. Pinafore, and Samuel in
The Pirates of Penzance. In 1916, he was given the role of Sir Marmaduke Pointdextre in the company's new production of
The Sorcerer, giving up Luiz. Later that year, he swapped some of his smaller roles for larger ones: the Boatswain for Dick Deadeye in
Pinafore, Samuel for the Pirate King in
Pirates and Cholmondeley for Sergeant Meryll in
Yeomen. His last new role, in 1918, was the title role in
The Mikado. When D'Oyly Carte returned to the
West End in London for its 1919-20 season, after 10 years on tour, Hobbs played Sir Marmaduke, Dick Deadeye, the Pirate King, the Colonel, Mountararat, Arac, The Mikado, Sergeant Meryll and Giuseppe.
The Times called his Pirate King "terrific". ==Later years==
