Even if there are a thousand exceptions, the point rings true. Sharing the space of a band with a figure such as Debbie Harry can definitely result in overshadowing. A lot of people, I believe, regard Stevie Nicks as the definitive face and voice of Fleetwood Mac, and she was not even in the band for their formative era(s).
The British music press never even bothered to learn the names of the musicians in Sleeper, just referring to them as "Sleeper-blokes" at the height of their Britpop fame.
