Jim,
Eddie Lenihanes appearance is not relevant.
You have no right to sneer or make disparaging remarks about a performer based on their appearance.
If you are not acquainted with Brian Peters singing,then you should become so ,if you wish to talk about revival singers you need to keep up to date.
In fairness,you should name the singer who presented in Praise of Ballads,and the year, so that if they wish they can reply,They may have changed their views,likewise the other singer mentioned.
I prefer to go by what my ears tell me when I am listening to a singer/Performer,not their appearance.
