Hello Mick, Your quote above made me think of this clip on Youtube.
The English guy talking on here is Dr Oliver Sacks, a Neuroligist and Author, I've read his book Musicophilia: Tales of Music and the Brain.
Watch the wonder of Henry coming alive when listening to his favourite music. When the headphones are taken off Henry talks passionately about Cab Calloway and starts singing. His whole mood transformed from nearly mute to expressing what it means to him "It Gives Me The Feeling Of Love", he can't stop talking. All this just through a few songs, it's incredible what music can do for you.
Mick, I wish you all the best with your health my friend. Music is medicine, to be taken everyday.
