Playing at fly-half, Bush is regarded as one of the most talented Welsh players of the pre-First World War era.

[2] Bush played most of his career for Cardiff RFC making 171 appearances and scoring 66 tries between 1899 and 1913.

He won eight caps[3] for Wales (1905–1910), including for the famous Match of the Century, the 1905 victory over New Zealand.

He was the undoubted star of the tour, being dubbed 'Will o' the Wisp' by the Australian press for his devastating play.

Bush failed to improve in his second match, played against Berkshire at the Cardiff Arms Park in 1902; scoring a single run in his only innings.
