Multiple authors - and not &

I’m submitting something to a journal and they request references are “and” not & (they use a version of harvard). Since they do specify a specific style, I cannot see an easy way of doing this which is either not manual or requires the user to try and find a harvard style that uses this convention?

Best,

The “Harvard - Cardiff University” as well as many other styles do this. For future reference, you can often find the style you are looking for by using this search engine: http://editor.citationstyles.org/searchByExample/
