In the course of putting these compilations together I listen to hours of playing and as has already been said "Singing with Accompaniment".
I firstly listen to the singing voice and then the accompaniment and if both are OK then I put the recordings forward for selection in the final line up.I must admit I never listen to the pronunciation and here is the difficulty.Being raised in London I like many others find Dick Van Dyke's attempt at the Cockney accent laughable.A fine example of brilliant singing and accompaniment, but is spoilt by the pronunciation.I would never pick up upon an artist from America for example badly pronouncing an Irish song,although once again it had all the requisites that would make me include it.So here would be a classic example of the Irish disliking a recording for this reason.In America however they would love it.You have broadened my thinking, but I am not sure I could ever implement it.Unless the song is Cockney or from Sussex.
