Er Ian mate...I heard you at karaoke!
Can I suggest the following:
Silence is Golden - The Hollies
The Sound of Silence - Simon and Garfunkel
Enjoy the Silence - Depeche Mode
Feel the Silence - The Goo Goo Dolls
Listen to the Silence - Bruce Hornsby and the Range
The whispering part of Careless Whisper - George Michael
The complete unfinished bit of the Unfinished Symphony
320 bars Silence by Stockhausen...a piece where the performer sits at a grand piano for 32 minutes and plays not one note!
