Ok somebody else gave it a shot and it sounds a lot beter than my interpretation:
"The song that needs the opal sound, I'm here to see Pearl Jam
They're giving me a believer again....I'll never say never again
They're making me a believer again...in rock, rock, rock, rock, rock, rock, rock, rock, rock, rock, rock, & roll, roll, roll, roll, roll, roll, rollll!"
*Note the definition I found for opal - A gemstone made of this mineral, noted for its rich iridescence....A rather nice complement for PJ...
well at least I tried
