All in One Voice

All in One Voice is the twelfth studio album by Welsh singer Bonnie Tyler. It was released in 1998 by EastWest Records, following her previous album with EastWest, Free Spirit (1995). The album remains the least commercially successful in Tyler's career as it failed to chart worldwide.

Recording
Tracks produced by Jimmy Smyth were recorded at Full Moon, Westland and Park House Studios in Dublin, Ireland. "The Reason Why" was recorded at Boogie Park Studios in Hamburg, and "I Put a Spell on You" was recorded for Mike Batt's album Philharmania at Abbey Road Studios in London. The remaining tracks were recorded at Red Deer Studios in Germany.

Singles
"He's the King" was released ahead of All in One Voice in December 1997. The song was originally used for the German TV series The King of St. Pauli. Tyler made an appearance in one of the episodes performing the song in a casino. "He's the King" spent one week on the German Singles Chart at number 95.

"Heaven" was released as the second single in 1998. The song was first performed at Melodifestivalen 1997—Sweden's national selection competition for the Eurovision Song Contest—by N-Mix, under the title "Där en ängel hälsat på" (Where an angel has visited in English), where it came 2nd.
