Which band's keyboardist and drummer were married to the identical twin sisters Jacky & Vicky Gibbs?

John Douglas Lord (9 June 1941 – 16 July 2012) was an English orchestral and rock composer, pianist, and Hammond organ player known for his pioneering work in fusing rock with classical or baroque forms, especially with the British rock band Deep Purple. Lord's second wife, Vickie Gibbs, was a former girlfriend of Purple bandmate Glenn Hughes and twin sister of Ian Paice's wife, Jacky Paice (founder of the charity Sunflower Jam). The sisters' father was Frank Gibbs, owner of the Oakley House Country Club in Brewood, South Staffordshire.

Ian Anderson Paice (born 29 June 1948) is an English musician, best known as the drummer and last remaining original member of the rock band Deep Purple. He is often cited as one of the greatest drummers of all-time. He remains the only member of Deep Purple who has served in every line-up since the band’s inception in 1968, as well as having played on every album and at every live appearance.

Paice is married and has three children. His wife, Jacky, is the twin sister of the late Jon Lord's wife, Vicky.
