Ready for Harry Potter and the Canadian Folk Act? Well, it could be coming to a courthouse near you, if a Winnipeg band called the Wyrd Sisters have their way. The 15-year-old, Juno-nominated folk group is suing Warner Bros., the studio behind the upcoming Harry Potter and the Goblet of Fire, because that film reportedly features a musical act of the same name.

In the book, there is a popular band called the Weird Sisters (note the different spelling), but a Warner Bros. spokesperson says the musical act in the film isn’t identified, although, FYI, look for Pulp’s Jarvis Cocker and Johnny Greenwood and Phil Selway of Radiohead among the movie band’s members.

The Wyrd Sisters want the filmmakers to change the band’s name, or help them in establishing a new identity, and seeks to block Canadian distribution of the film until the case is settled, according to a story in Canada’s Globe and Mail newspaper.

So what do you think? Do the Wyrd Sisters have a legitimate gripe, or are they just riding the Harry Potter bandwagon to wider recognition?
