1985–1986 school year
By the 1985–1986 school year, Hogwarts students Myron Wagtail and Kirley Duke, accompanied by Orsino Thruston, had formed the band, and wanted to perform in the Hogwarts Castle. They wanted Jacob's sibling to perform with them, though the student was unable to actually play an instrument. As part of the preparations from the show, they taught Jacob's sibling to transfigure a cauldron into a bass guitar and charm it to play on its own. When asked if they used the charm they denied it, claiming to have learned through years of practice. 
1986–1987 school year
In 1986–1987 school year, the band mentioned that Jacob's sibling, being known as an unofficial "Curse-Breaker", had been one of their sources of inspiration. They helped them practise their Frog Choir audition on the training grounds. They then encouraged Jacob's sibling to sing in front of Professor Snape to test their nerves. They watched and praised them for having done a great job.
1989–1990 school year
During the 1989–1990 school year, the Weird Sisters popped up in front of Jacob's sibling in the Three Broomsticks Inn when they thought they had mentioned something about them. Later, Jacob's sibling invited the Weird Sisters to do a concert at the Great Lake. They also performed during the party at Three Broomsticks.
1994–1995 school year
Upon the announcement of the Yule Ball, one of the rumours discussed in Hogwarts School of Witchcraft and Wizardry was that Albus Dumbledore had booked the Weird Sisters for the ball, which turned out to be true.
On 25 December, 1994, the band performed in the Great Hall on a magically-appearing stage. Among the band's instruments were a set of drums, several guitars, a cello, a lute, a double bass and some bagpipes. During this performance, Harry Potter noted that all members of the band were extremely hairy and all wearing black robes that had been artfully torn.
1995–1996 school year
Behind the scenes
- In the film adaptation of Harry Potter and the Goblet of Fire, the band which performs at the Yule Ball deliberately goes unnamed throughout the film because of a legal dispute between the film studio and Canadian folk band Wyrd Sisters. The band is simply introduced as "The band that needs no introduction!", by Filius Flitwick.
- Members Merton Graves and Herman Wintringham do not make an appearance in the film.
- In the film adaptation of Harry Potter and the Goblet of Fire, piper Gideon Crumb plays keyboards as well as bagpipes. In the book series, however, there is no mention of the band having a keyboard player.
- The band's songs were written by Jarvis Cocker, who plays singer Myron Wagtail. "Do the Hippogriff" was a collaboration between Cocker and rhythm guitarist Jason Buckle (Heathcote Barbary).
- The Scottish band Franz Ferdinand, self-professed fans of the books, were originally invited to play the Weird Sisters.
- In an interview, J. K. Rowling stated that the instruments that they played included bagpipes, cello and electric guitar and that they were Harry Potter's favourite band.
- At least as portrayed in the Harry Potter films, the Weird Sisters are considered to be a wizard rock band.
- All appear on Chocolate Frog Cards at the Harry Potter Exhibition.
- The term "Weird Sisters" was the name given to the three prophetic witches in the play "Macbeth," by William Shakespeare ("weïrd" being Old English for "fate" or "destiny").
- Macbeth, stated to be quite possibly the favourite Shakespeare play of Harry Potter series author J. K. Rowling, had another allusion in Harry Potter and the Prisoner of Azkaban (film), where the Frog Choir sings "Double Double Toil and Trouble", a direct quote from the play.
- Interestingly, the Spanish edition of the books refers to the band by the name las Brujas de Macbeth, meaning "Macbeth's Witches".
- As it is unconfirmed as to from where J. K. Rowling got the idea for the band's name, other possibilities include:
