I thought this was already popular when it was released the first time (even if it was more popular the 2nd time).

On its initial release it was unsuccessful. Two versions have achieved chart success:
1) 1972
2) 1992, 20 years later - an acoustic version by Eric Clapton on his album Unplugged that won the 1993 Grammy Award for Best Rock Song.

Originally released in 1982 on the album Saints & Sinners, it was re-recorded in 1987 with minor changes in the arrangement and was re-released on the album Whitesnake 87, and became a hit in 1987-88.

Originally a single released in 1987, it became a hit in 1992 when it was chosen to be the anthem of 1992 Olympics in Spain and was featured at the opening ceremony. It was also used as the title music to the BBC's coverage of the 1992 Summer Olympics.
Mercury died about six months before the Olympics.
The song is about Freddie's love of opera and he performed it with the operatic soprano Montserrat Caballé. The song is one of the greatest rock-related vocal performances.
