Poets often get it wrong, and in songs:

P. McCartney in "Live and Let Die" sings:

" .. this ever-changing world in which we live in..."

The old song "Bonnie and Clyde" by Georgie Fame, from the 60s:

"... while Bonnie loaded the dollars into the dewlap bags ..." He'd meant "burlap", a type of sacking. Dewlaps are the hanging flaps of fat on an old person's face, like those of a hound dog. Ha! Ha!
