I thought this would chart much higher. The song is old-fashioned and sedate but Amy put in a fine performance, there is the charity angle and the video is quite touching.
There will undoubtedly be more 'last' recordings released as they work through her demos but this is probably the last thing she fully completed before her death. As such, I'm surprised at the terrible performance (surely a number 40 chart position reflects only low thousands of sales).
