Surely, of the Wesleys, John was the preacher, Charles the poet and Samuel the musician?

I remember hearing John's advice to the bald (a subject dear to my heart) in a book of nostrums against everything from "women's flux" to the common cold. Paraphrasing freely from memory, it began "Rub into the pate a mixture of honey and ground raw onion...". Stick to advising on singing, John.
