Jazz from the smiling guy that was written in 1952 and entered the collection of 1954 from Three Blazers band. Their name, as well as their appearance suggests that they are more like gangsters, not singers. But then half of US was like this – dapper toffs who very much looked after their outward appearance. However, in this outfit they couldn’t walk in some places – worrying about the safety of their blazers. Or about a thin mustache under the noses.
