On his return from the war Glynne mainly appeared in concert singing, primarily concentrating on ballad and oratorio.[4] He made a number of appearances at the Henry Wood Promenade Concerts at the Royal Albert Hall, including in 1917, 1919, 1920, 1923, 1928 and 1930.[5] He was one of the first singers in the United Kingdom to broadcast in the new medium of radio,[6] which he did from Marconi House,[7] forging a successful career on the airwaves owing to the clear tone of his voice. Glynne sang in the lyric concerts organised by Boosey and Company, Chappell & Co. and Cramer & Co. in London and made a number of appearances on the concert platform singing in oratorios.[2]
After the war, Glynn was also in demand as a recording artist, and he became particularly well-known for his recordings of ballads. In 1921 Glynne gained a recording contract with HMV at the suggestion of the company's music advisor, Sir Landon Ronald. Also in 1921 he married Helena 'Lena' Evans, with whom he had three children. He was involved in making a complete recording of The Pirates of Penzance (1920) conducted by George W. Byng; sang in the chorus for the recording of Patience (1921) and other early recordings of Gilbert and Sullivan by HMV again conducted by Byng;[9] shared Ralph Rackstraw in the 1923 acoustic recording of H.M.S. Pinafore; sang Leonard Meryll and a portion of First Yeoman in The Yeomen of the Guard (1928) and Samuel Coleridge-Taylor's Hiawatha's Wedding Feast (1929) under the baton of Malcolm Sargent. In 1935 he recorded arias from Handel's Messiah. He made a number of recordings for the Welsh market including parts from Blodwen by Joseph Parry in addition to a number of Welsh ballads, sometimes accompanied by the Welsh Miners' Quartet from Llanelli.[2]
