The article text provided could not be retrieved — the content supplied consists only of website navigation menu items (Music, Film, Travel, Art, News, Shop, Mailing List) repeated twice, with no actual article body about Joe Strummer or the singers he reportedly admired. As a result, there is no substantive content available to summarise.

To provide an accurate summary, the full article text would need to be supplied, as the current material contains no details about which singers Strummer discussed, the context of his comments, or any supporting quotes.
