One on One is a 1979 collaboration album by jazz keyboardist Bob James and guitarist Earl Klugh that won the Grammy Award for Best Pop Instrumental Performance in 1981.

The album was released in late 1979 by Tappan Zee, the label owned by Bob James, promoted and distributed by Columbia in the US and CBS in the UK.

"Jazz Jam" was a throwaway track assembled by James for the engineers to balance their recording levels.

"Jazz Jam" remained unreleased until Bob James found it while re-releasing the album for the Japanese market.

"Jazz Jam" was remastered for the 30th anniversary release of the album in 2009 in the US and Europe including the UK.
