Just checked the page and log for it, and it seems it was me who added Halford as a pseudonym to Rob Halford two years ago...

(And placed the link between the one page and the other)

...When an artist goes by a single name, or part of that name, as in this case, I look to see if they have also released anything under the full name, which he has... and then include the partial name under the full name, and link it.

/Partly the reason for this, is when you look at Judas Priest (or other band name) of which that artist was / is a member, I try to get the full names for the band members at the head of the page, which you can then link to and see what he / they have released under their full name, partial / pseudonym name, any collaborations (likely under full name, plus whoever they were collaborating with) and links to any other bands / projects they were involved in.

It makes for a generally practical and practicable rule than can be applied in most, if not all cases, for consistency's sake, across site, regardless of which artist (s), so there is a consistency of method in the search process.

I have added "Fight" as a link to Rob Halford's page, alongside Judas Priest, and found one track for "Two", but am not sure if this is the same band you're looking for ;)

Let me know here if any other links with other artists / bands need to be made for him, and, in the words of Batman: "I'll look into it"
