Hi Eliza,regarding "What a mouth",a great song,Harry Champion made it famous,and Tommy Steele picked it up from an act known as " The two Bills from Bermondsey". I found their recording of it on a 78rpm record MANY years ago,and also recorded it myself (ALSO many years ago)
A lot of Harry Champion's songs are available on cd now,and there's some wonderful stuff,LOTS of words to get yer 'ead around though!!
