If have a list with all the prefixes, and all you want is a list without the number prefixes you can open the list in Word and use "Table - Sort" to put the tune names in order. If you sort by paragraphs, all the ones with numbers at the front will be somewhere together, or in a few clumps.

Select (highlight) the ones that have prefixes and Use the Word "Edit - Replace" to delete the prefixes, and the whole list again.

As an alternative, you could use the "Edit - Replace" to to put a tab immediately after the prefixes and a tab at the beginning of each line that doesn't have a prefix, so that all the song names are in the "second column" and then use Table - Sort but sort on "field 2". The Table - Sort function works for columns separated by tabs (or whatever separator you choose) without the necessity of putting the list into a table.
