I completely disagree with saying there was "no talent" on the show. More so comparing it to today. That is like comparing apples to bananas. Agreed, sound qualtiy and technology wasn't what it is today. How is that a disclaimer on the talent on the show? Some of what I hear called talent today is just noise. There probably is talent, but abused or misplaced.
Also, the type music was different, more of a big band/orchestra sound. Each era of music is a stepping stone to the next and they all serve a purpose. A Grammy doesn't necessarily mean talent, either. It is all subjective, depending on what we like at the time. There have been Grammy winners I thought sucked! It is more based on popularity.
Lawrence Welk and his crews had talent, though a different type with a different genre of music. I don't see any of us on TV making music for the number of years they did, and still making.
Now, getting off my soapbox!
