Shades of Ian Hunter: The Ballad of Ian Hunter and Mott the Hoople is a compilation album by Ian Hunter, consisting of tracks by Hunter's previous band Mott the Hoople, and solo Hunter tracks as well.
 It was released in 1979 as a double-LP.

The Windsor Festival was founded in 1969 with Yehudi Menuhin and Ian Hunter as Artistic Directors and Laurence West as Executive Chairman.
 The original idea for the Festival was put forward by Ian Hunter to the Dean of Windsor in 1968, building on the participation of the Menuhin Festival Orchestra with Yehudi Menuhin using St George's Chapel, the State Apartments of Windsor Castle and the Theatre Royal.
 The Dean formed the Windsor Festival Society, which then moved to plan the first festival.

Ian Hunter Patterson (born 3 June 1939), known as Ian Hunter, is a British singer-songwriter who is best known as the lead singer of the English rock band Mott the Hoople, from its inception in 1969 to its dissolution in 1974, and at the time of its 2009 and 2013 reunions.
 Hunter was a musician and songwriter before joining Mott the Hoople, and continued in this vein after he left the band.
 He embarked on a solo career despite ill health and disillusionment with commercial success, and often worked in collaboration with Mick Ronson, David Bowie's sideman and arranger from the "Ziggy Stardust and the Spiders from Mars" period.
Short Back 'n' Sides is the fifth solo album of Ian Hunter.
 Unsure of which direction he should take, Ian Hunter finally decided to collaborate with Mick Jones, who gave Hunter's songs a tougher and heavier touch.
 Fellow Clash member Topper Headon as well as Mick Ronson, Todd Rundgren and Ellen Foley also appeared on this album.
Stuart Lee Murdoch (born 25 August 1968) is a Scottish musician, writer and filmmaker, and the lead singer and songwriter for the indie pop band Belle and Sebastian.
Ian Hunter is the first solo album by Ian Hunter, recorded following his departure from Mott the Hoople.
 Released in 1975, it is also the first of many solo albums on which he collaborates with Mick Ronson.
 The bassist, Geoff Appleby, was from Hull like Mick Ronson and they had played together in The Rats in the late 1960s.
Dog on Wheels is the debut EP by Belle & Sebastian, released in 1997 on Jeepster Records.
 The four recordings on the EP actually pre-date the band's début album "Tigermilk", produced whilst bandmembers Stuart Murdoch and Stuart David were on the Beatbox music course in Glasgow.
 Murdoch, David and Mick Cooke are the only long-term members to play on the songs, though Cooke only appears on the title track.
 The drums were supplied by David Campbell, whilst Brian Nugent played flute on "String Bean Jean", and Gerry Campbell, a tutor at Beatbox, provided keyboards on "The State I Am In" and "Belle & Sebastian" as well as lead guitar on "String Bean Jean".
 Other contributors to the E.P. include Mark McWhirter, Michael Angus and David Mackenzie, though their roles have not been confirmed.
