So, are you folks suggesting that the Manfred Mann versions are all better than the originals?
From a production point of view, the Manfred Mann versions are arguably a bit more refined. But I'd say that the Springsteen originals are far and away more definitive and honest performances compared to the Manfred Mann's overt commercialized treatments. In particular, the Manfred Mann cover of "Blinded By The Light", though more radio friendly, is embarrassingly silly with its lyric changes.
And just to be clear, although I'm a fan of Manfred Mann, and the fact that I actually do like those covers, they certainly don't overrule the originals.
I always admired MM`s ability to adopt songs and convert them into something completely different from the original. He did a good job with Bruce`s songs, of whom he is a fan apparently. Another example is Demolition Man, which has almost nothing in common with the original from The Police.
