All that can presently (July 2022) be gleaned about Amy Clevere from sheet music covers and by Internet searching is that she was presumably an English actress/singer who has been featured on 8 works published between 1898 and 1911.
Her portrait on the left is taken from a daily newspaper cutting published in 1903 as is the following amusing description.
Miss Amy Clevere: is an extremely attractive young lady who sings of "The Girlie with the Baby Stare". The girlie in question it appears, adopts the stare merely by way of effecting an extreme innocence which her record and experience do not justify. When references are made to complicated cases inthe law courts the girlie at once puts on the "baby stare" in the hope that you will go into full particulars with the confident impression that she will not know what you are talking about. The subject, perhaps, is rather a intricate one, and this is, of course, no place for metaphysics. Miss Clevere's second song is a serenade which she renders in the costume of poetical youth and. which has a chorus to the effect that"l am longing, love, for you-oo-oo" That "yoo-oo-oo" is practically the history of the modem musical comedy. I don't know what we should have done without it.
