James Stewart Bain (19 December 1947 – 23 January 2016)[1] was a Scottish musician, best known for playing bass guitar in the bands Rainbow and Dio.

[2] He also worked with Kate Bush and Thin Lizzy frontman Phil Lynott, co-writing on his solo albums.

Bain was born in Newtonmore, Badenoch and Strathspey, Highland, and played in several provincial amateur bands as a young teen.

Jimmy was the lead vocalist, songwriter, as well as bassist for the band, which also included ex-Thin Lizzy guitarist Brian Robertson, drummer Clive Edwards (Pat Travers, Uli Jon Roth's Electric Sun) and guitarist Neil Carter (who went on to UFO and Gary Moore).

Jimmy then worked with the former Family main-man Roger Chapman, Roy Harper, Gary Moore, and Kate Bush (on 1982's The Dreaming).

He was secretly brought in by the German hard rockers Scorpions to play bass guitar on their 1984 album Love at First Sting.

[3] Bain co-wrote several other songs for the following albums, The Last in Line (1984), Sacred Heart (1985), Intermission (1986), Dream Evil (1987) and Killing the Dragon (2002).

In 2005, Bain again joined forces with former Black Sabbath and Dio drummer, Vinny Appice, for two projects, The Hollywood All Starz and 3 Legged Dogg.

In an interview with journalist, David Lee Wilson, Bain lamented Appice's eventual choice to leave both these groups so that he could tour with Ronnie James Dio in the Black Sabbath offshoot, Heaven and Hell.

The band Last in Line was put together in 2013 comprising Bain, Viv Campbell, Vinny Appice, Claude Schnell and Andrew Freeman.
