Love the McGarrigles and play various of their songs. Usually sing Kiss and Say Goodbye as a first song at gigs with our band. Heart Like a Wheel. Swimming Song. Blues in D (which I play in Bb). Foolish You. But my favourite could well be Sodium Chloride which I see I sat down and worked out how to play back in 2005 and it has never been played! The words are so clever and a lovely rolling feel to the song. But we have talked about it so there's another mission...

G]Just a little [D7/A]atom of chlorine, valence [G/B]minus one[D7/C]
[G]Swimming through the [D7/A]sea, diggin' the scene, just [G/B]havin' fun[Gaug/B]
[C]She's not worried about the [G/D]shape or size of her [C/E]outer shell--
[C#dim]it's fun to ionize
[G]Just a little atom of [D7/F#]cl with an unfilled [G]shell. [G7]

And the middle bit -

Then [F/G]unsuspecting chlorine felt a magnetic pull
She looked down and her outside shell was full!
[A7]Sodium cried "What a gas, be my bride,
And [D]I'll change your [A7]name from chlo[D]rine to [A7]chlo[D7]ride!"
