Heavy rock group Black Sabbath is set to have their first number one album for 43 years.
The band, fronted by Ozzy Osbourne, last attained the feat when their second release, Paranoid, was released in 1970, which featured signature tracks such as War Pigs and Iron Man.
The new album 13 reunites original members Osbourne, Tony Iommi and Geezer Butler for the first time in 35 years, although they have released other recordings during that time with others.
The comeback album is at number one in the midweek album chart, according to the Official Charts Company, and is expected to remain there at least until the weekend.
Osbourne, who had some problems in his marriage earlier this year as a result of a temporary return to drinking, said: "I can't believe Black Sabbath may have its first number one album in 43 years."
Black Sabbath are to tour the UK in December, including a homecoming show at Birmingham's LG Arena.
