Helen,Manfred Mann was covering Bruce Springsteen's "Blinded by the Light" which appears on Bruce's _Greetings from Asbury Park_ album(1973). The line is "...And she was blinded by the light/Cut loose like a deuce another runner in the night/ Blinded by the light..."
I will admit that I love Bruce (I spent my formative years in New Jersey-what can I say?) and knowing the words sure doesn't help me understand the meaning! I always sort of thought it ha d something to do with numbers running or drug use or ????
Hope this helps a wee bit :-)
