[6] Green advertised in Melody Maker for a bassist; Bob Brunning answered the ad, but contacted the wrong phone number due to a misprint in the newspaper.

Brunning secured the role as the bassist for Fleetwood Mac on the understanding that he would leave if McVie changed his mind and agreed to join, and was informed by Green that their first performance would be at the Windsor Jazz and Blues Festival.

[7] Shortly after Fleetwood Mac's live debut, McVie left the Bluesbreakers following Mayall's decision to add a horn section to the lineup.

McVie subsequently joined Fleetwood Mac, replacing Brunning, whose bass parts were unused on the final album with the exception of "Long Grey Mare".

An additional recording session took place on December 11 that yielded "My Heart Beat Like a Hammer", "Shake Your Money Maker", and "Leaving Town Blues", although the latter song did not make the album.

[13] Upon release, Barry Gifford (writing for Rolling Stone) praised the album, and described it as "potent enough to make the South Side of Chicago take notice".

[15] The Telegraph has described the album as a "classic sixties London 12-bar blues rock debut", while also calling it "raw, physical, high spirited and blessed with the exceptional playing of Peter Green".

[17] AllMusic noted the influence of Elmore James on Spencer's compositions and wrote that Green's "inspired playing, the capable (if erratic) songwriting, and the general panache of the band as a whole placed them leagues above the overcrowded field.

"[9] In 2023, the album received renewed attention after "I'm Coming Home to Stay", a bonus track featured on the 1999 re-release, was used in the third episode of the HBO television series The Last of Us.
