Then that brought me to think about the different feeling of playing Piano (Acoustic) that you can't really do much with the keys compares to playing Guitar (Acoustic or even Electric) particularly when you have to bend the strings while playing Blues.
Here's Leon's acoustic piano and John M's bending notes on guitar;
SONG FOR YOU
I've been so many places in my life and time
I've sung a lot of songs, I've made some bad RHYMES
I've acted out my life in stages
With ten thousand people watching
But we're alone now and I'm singin' this song to you
I know your image of me is what I hope to be, baby
I've treated you unkindly but girl can't you see
There's no one more important to me
So darling can't you please see through me
'cause we're alone now and I'm singin' my song for you
You taught me precious secrets of the truth, withholdin' nothin'
You came out in front and I was hiding
But now I'm so much better so if my words don't come together
Listen to the melody cause my love's in there hiding
I love you in a place where there's no space or time
I love you for my life, 'cause you're a friend of mine
And when my life is over, remember when we were together
We were alone and I was singin' my song for you
