How to Delete String inside Parens and preceding space

Sorry new to scripting, could not find in community - I have a number of titles that have a song title followed by a space and a string inside a set of parens (). The string is of differing lengths and content.

I would like to rename the title, retaining the song title but deleting the parens, the string inside the parens and the preceding space.

Thank you for any help.
