The late Queen fronter Freddie Mercury will have a lyric-filled notebook auctioned off by Bonhams in the U.K. The pad, used between 1988 and 1990, features lyrics for tracks such as "Too Much Love Will Kill You" and "The Show Must Go On."

The latter song was recorded in November 1991, just six weeks before Mercury's death from AIDS.

"We see and sell lyrics from all sorts of different artists but they tend to be one piece of paper for one song," said a rep for Bonhams.

"To have a notebook which contains tracks recorded over a three-year period is really exceptional. I can't think of another one."

The notebook, estimated to sell for between £50,000-£70,000, hits the block on June 29.
