Remove track number from front of artist field

I have a number of mp3s, and in the artist field I have track numbers in front of the artist name.

Is there a way of removing the track number only, in bulk?

Yes.

If you show us a real example, we can tell you a working solution.

Filename: 08 Front 242 - Headhunter
Title: Headhunter
Artist: 08 Front 242

How do I remove the '08' which is in front of artist 'Front 242'?

You could try it with
Convert Tag -> Tag
Field:
ARTIST
and the formatstring:
$regexp(%ARTIST%,\d+ (.*),$1)

This would look for a number and a space in ARTIST and replace it with the following content only.
The format string only works if you really have a number and a space in front of your ARTIST tag.

Please be aware that this would also remove the number from valid existing ARTIST names with a leading number like 10 Poets or 100 Monkeys and others

It didn't work but I should have added which will most probably make a difference:

There is a "." after the 08

So in the artist field it shows: 08. Front 242

Would the formatstring have to deal with the "." aswell?

Do you have this dot in the filename too or only in the ARTIST tag?

If the dot is only in the ARTIST tag you can use this format string:
$regexp(%ARTIST%,\d+\. (.*),$1)

If the dot is also in the filename as
08. Front 242 - Headhunter
then you could also use Convert -> Filename-Tag with the format string
%TRACK%. %ARTIST% - %TITLE%

Thanks for your help.
That did what I wanted.
