Harry Hood is from the Hood Dairy Company, a New England milk company based in Boston. The members of Phish lived next to a Hood milk plant. "You can feel good about Hood" was the company's slogan.
The line "Harry, where do you go when the lights go out?" was Brian Long's contribution. Others have said the line refers the lights at the plant going out at some point each night.
The thank you to Mr. Miner was possibly from the person who lived in the house before the band. Phone calls and letters would come for him and one caught the band's eye, a letter began with "Thank you Mr. Miner."
The audience often had glowstick wars when Phish played this in concert. (thanks, kyler - berwyn, PA, for all above)
