English baritone jazz and light music singer. The recording career of Robert Carr spanned from around 1904 to the late 1930's. Some sources think that Harry Trevor was a pseudonym used by Carr, yet it was never truly confirmed.
As well as his own names many recordings were issued under pseudonyms, e.g. Robert Oswald, Harry Durrant, Robert Durrant, William Duncan, Richard Condor, Ernest Gray, Bobby Gray though those names sometimes concealed the identities of other singers as well.
