Sometimes on those "classic" tunes they speeded them up or down and changed the pitch. Unlike the digital age today where a recording can be slowed and the pitch kept in tune.
Don't bitch to me about the economy while you're still buying Chinese products.
hey Al, check the internet for tabs, usually they tell if you if there is an alternate tuning, or have it tabbed for standard. It's been awhile since I've played it so I don't remember anymore. Good luck.
