Of course Mabel John’s original version of “Your Good Thing Is About To End” is so sensational it will always be the track against which all other renditions are judged. But perhaps my favourite cover is this Chicago one by Trudy Johnson. The tone and phrasing of her voice are just perfect for the angry and regretful tale, superb gritty touches as well. Also the crack West Coast musicians emphasise the bluesy chord changes so well helped by a very sensitive lead guitarist - Arthur Wright??
UPDATE ~ Davie Gordon writes with more info - "Trudy was originally from Oakland and got her start in the business as guest vocalist with The Spyders, a fine blue-eyed soul band who recorded for Leo DeGar Kulka's Golden State label. There are at least three tracks she recorded for Capitol that have never been released anywhere. She did a session in Los Angeles produced by Dave Cavanaugh and arranged by Phil Wright recording these three tracks "It Takes A Lotta Good Love", "I Feel Like A Woman" and "Let Me Be Good To You". These were recorded on Oct 16,1969 around the time the single was issued. Trudy's still working although she's now more in the jazz vein."
Bob McGrath has sent more info about the sessions that included the tracks on the Capitol 45. They were held on 20 May 1969 at Capitol's LA studio and the unissued cuts are "Never Let Me Go" and "Just Send The News".

As ever I'm grateful to Davie and Bob for their excellent info.
