Remove all words after specific character until space and dash

I have this file

Singer1; Singer 2; Singer 3 - Song Title.mp3

I want it to display only Singer1, so it'll be

Singer1 - Song Title.mp3

but some have 2 singers, some 3, others have more.

so, how do I do this?

I've yet to find a similar problem in this forum.

thanks beforehand

Replace ";.* -"
with " -"
Use regular expressions

(NB Do not type quotation marks)
