Dear Jon,
If i'm not mistaken, this is the 'Suvarnamala Stuti' composed by Adi Shankaracharya. It reads:
"Saamba Sadashiva Shambhu Shankara
Sharanam me' tava charana yugam"
search google using term 'suvarnamaala stuti' and u will get links to the text.
This composition has been rendered by Pandit JAsraj in his unimitable style in his album "Shiv Shambho"
