At the 10th "Grammy Awards" held in 1968, which of these recordings won for 'Best Instrumental Theme'?

Initially the recording of the theme tune "Theme from Mission: Impossible" was used for the American espionage TV series "Mission: Impossible" (1966–1973). This theme was written and composed by Argentine composer Lalo Schifrin and has since gone on to appear in several other works of the "Mission: Impossible" franchise, including the 1988 TV series, the "IM" film series, and several video game series.

The "Mission: Impossible" theme won for the Best Instrumental Theme at the 10th Grammy Awards held in February 1968. Schifrin also won the Grammy for Best Original Score Written For A Motion Picture or a Television Show. In 2017, the 1967 recording of the Theme from "Mission: Impossible" by Lalo Schifrin on Dot Records was inducted into the Grammy Hall of Fame.

Actually in the song's history, Schifrin's working title for it was "Burning Fuse". Schifrin would compare his writing process to writing a letter: "When you write a letter, you don’t have to think what grammar or what syntaxes you’re going to use, you just write a letter. And that’s the way it came." He estimated that he wrote the main theme in 90 seconds and completed the full arrangement in three minutes.

Martin Landau, who played Rollin Hand on the original TV series, attended the recording session. He recalled. "Schifrin was conducting and interrupted the band; he said, 'no, no, it should be like this.' They resumed and quickly recorded it. I was stunned; it was so perfect. I came out humming that tune."
