[INTRO  ]

F# C# Bb F (w/occasional slide up to D# after the C#) 

Last line of verse  

F# C# C F (listen for it just before solo/Chorus bit, there is a definite change in tone) 

Chorus/Solo bit 

D# C# Bb F 

Repeat this when there isnt singing and the elctronics are doing there bit; and when Eliza Doolittle 
sings swap back to the F# progression.  
I dont think this is perfect so any changes please be suggested below. Cheers
