So few details were available from these sessions but its been possible to establish the following with some degree of accuracy.
'Start Me Up' - First cut as a reggae track ( 'Never Stop' ) in 1975, redone as 'Start Me Up' for 'Some Girls' before reverting to a reggae arrangement again during the 'ER' sessions. In 1981, when going through old tapes, they decided to use the rock version. Its been often reported as coming from ER material from '79, but Chris Kimsey says its from around the same time as 'Miss You' which would date it as late '77.
http://www.soundonsound.com/sos/apr04/articles/classictracks.htm'Hang Fire' - first cut as a 6-minute rocker ('Lazy Bitch') for 'Some Girls', the released version comes from 'Emotional Rescue' sessions in '79.
'Slave' - Backing track recorded Rotterdam early 1975, hence the inclusion of Billy Preston & Ollie Brown. Overdubs added in Paris late 1980 and then Sonny Rollins sax and Pete Townshend's backing vocals would have been added in New York in spring 1981.
'Little T & A' - Originally cut in Nassau early '79, the released take comes from Paris later that summer. 'Emotional Rescue' sessions.
'Black Limousine' - Originally cut for 'Some Girls'. Finished Paris '79 for ER.
'Neighbours' - a new song. Recorded late 1980 in Paris. Sonny Rollins' sax added in New York, spring '81.
'Worried About You' - Basic track recorded early '75 in Rotterdam with Wayne Perkins on guitar. Overdubs added Paris summer 1979.
'Tops' - Basic track recorded either for GHS in late '72 (probably) or 'IORR' in late '73. Mick Taylor on lead guitar. Overdubs added Paris summer '79.
'Heaven' - A new track, recorded in Paris late 1980.
'No Use In Crying' - Paris, summer 1979
'Waiting on a Friend' - Basic track probably comes from Kingston late 72 (GHS sessions) although there's a school of thought it may come (or may have been first attempted) as early as 1970. Overdubs added in Paris late 1980 and then Rollins' sax would have been overdubbed in New York spring 1981.
As you can see from the article I've linked, Mick spent a month or so working on vocal overdubs for many of the songs with Chris Kimsey in a warehouse studio in Paris in spring 1981 (ie NOT Pathe Marconi) before the album got a few final overdubs and mixing in New York.
