The term "Sleeperbloke" should not pass without explanation
In the 1990s the music press came up with an expression to describe any anonymous gaggle of musicians hiding in the shadow of a more glamorous frontperson. They were dubbed Sleeper Blokes, in honour of those members of Britpop act Sleeper who somehow managed to be even less glamorous than vocalist Louise Wener.
There you have it. Any normal looking male would fade into the background standing next to Louise Wener--yesterday, today or tomorrow.
What a lovely lady.
