Sadly I was out for this, but what a delightful thread.
As @lolly can attest, Brotherhood of Man went on to have quite a fruitful post-Eurovision career, including this UK chart topper which is in no way inspired by a popular ABBA hit.
Figaro is the TITS (in a chicken in a basket cabaret style). And if Steps were described as 'Abba on speed', the dance routines were 'Brotherhood Of Man on crack'.
It's very much the Abba story hairwise as well, isn't it? Agnetha never changing hers for the first 6 years or whatever it was, and Frida having a different look in every video.
