You can sit down and be corrected if you like Magic. All of these Linda Ronstadt Greatest Hits compilations linked below and on the net that I have seen definitely have the words "with The Stone Poneys" on the inside sleeve notes for the track B1. So given the the guidelines indicate entering titles as they appear on the medium it would mean this track should be entered as Linda Ronstadt with The Stone Poneys.
The original single of Different Drum was released as by The Stone Poneys featuring Linda Ronstadt. So historically there has always been a delineation between the singer and the band. Other releases on the linked pages will confirm that.
There seems to a lot of autocorrecting going on on the site but it might pay to remember that on 45 Worlds we enter things as they appear on the medium warts and all. We do not correct spelling mistakes or add first names to composers or correct composer credits if they are wrong or missing. We enter everything as it appears on the copy at hand and refrain from showing off our superior knowledge. If we know better and some of us do the place for informing others is in the comments.
AS far as the credit for track B1 on all of these Greatest Hits issues go, as I understand it, The Stone Poneys were the band she was a part of... rather than: Linda Ronstadt And The Stone Poneys...
(I stand to be corrected, of course)
...And it should probably follow, that as this is an assemblage of original recordings, that track was done first as the Stone Poneys. It's inclusion here as Linda Ronstadt With The Stone Poneys is only to assure us of the fact that some other random band that doesn't include her has made it's way on to this issue.
So it seems to me that leaving them purely as The Stone Poneys is correct?
