I agree with that Don, and what I sometimes do is go through just the first stanza (and chorus) of my repertoire - playing a line then singing a line straight after...and, from my 3rd favourite genre, I remember seeing a clip from an opera (?) where Joan Sutherland follows a transverse flute, in a similar (if much more sophisticated) way.
To DS: some may not like me questioning women's tennis in the last stanza of that poem - but I have hit a lot of tennis balls myself and know that it does, indeed, put a lot of strain on the racket arm; thus, in my opinion, table tennis is a better sport for females.
