There's that perennial misnomer in the UK suggesting Americans do not get irony. While one gets why such a misguided Anglo assumption exists about the former colony that is the US, it probably has more to do with snobby British elitism and envy regarding a territory that was theirs but is no longer.
Now How To Dress Well's song and video for Precious Love (Thank You) must be rife with the self-knowing absurdity that lead singer Tom Krel emanates at every level. From the cheesy staging to the anachronistic singing style, Precious Love screams parody of the highest order. There is no way any of this pantomime is being played for real; tongue has to be locked firmly in cheek.
There is, however, the danger that all of this is an earnest paean to Krel's shocking sense of self-importance, but that would just be embarrassing to all involved. I mean, who'd even call themselves 'How To Dress Well' and do it with a straight face?
