#6 - Shirley Bassey - You'll Never Know
Since the following Chart Entry is from 1943, I feel it should be removed fromthis 1961 recording and transferred to one of the 1943-1944 recordings (I'm not sure how you determine which one). 1. UK 40's Sheet Music - 3 - 12 weeks (Aug. 1943).
OK so Shirley Bassey is clearly wrong, the suggested alternate (in the original source) was Alma Cogan who also seems 10 years too late, other sources suggest Texas Jim Robertson or Harry James. Given the success that Dick Haymes had with it in the US we'll go with him

#5 - (The Song Spinners) should be combined with #1 (Dick Haymes). Per Wikipedia & Joel Whitburn they were the backup vocalists for Dick Haymes.
Data fixed, thanks
In fact we've also fixed "In My Arms", "It Can't Be Wrong", "Nature Boy", "Put Your Arms Around Me Honey" and "You Can't Be True, Dear",
