“What's the New Mary Jane” is a nursery rhyme-like song, one of John Lennon’s most peculiar offerings. It was recorded for late 1968’s double album The Beatles (i.e. the White Album) but, literally, did not make the cut. Nonetheless, John Lennon would not let it go.

George & James was originally released in March 1984. Stars & Hank Forever! emerged in October 1986. The two LPs were parts of – and, as it turned out, the only entrants in – a series of albums their creators, San Francisco’s Residents, designated the American Composer’s Series.

The booklet coming with Just Like Gold - Live At The Matrix frequently refers to the band as “The Solution.” It will be the same here.

With respect to the name this pioneering San Francisco psychedelic outfit did choose, their drummer John Chance is quoted in the booklet as saying “My mother was really upset about it [the band’s name], and I knew why.”

One of the more interesting tracks on Paul Weller’s fascinating new cover versions album Find El Dorado is his interpretation of “When You Are a King,” originally a 1971 hit for White Plains, an ensemble which evolved from the touring version of “Let’s go to San Francisco” hitmakers Flowerpot Men. White Plains, it turns out, are represented on another new release.

The Pale Fountains played their first live show on 12 February 1980 as the support to on-the-up fellow Liverpudlians Wah! Heat. Their final stage appearance – notwithstanding the odd reunion – was on 21 May 1987 at their home city’s The Majestic Club, a venue which also traded as Mr Pickwick’s

Wheels of Fire was Cream’s third album. Issued in the US in June 1968 and in the UK two months later, it was a double LP. One record was of live recordings, the other of studio material. Of the nine tracks on the latter, three were co-written by the band’s drummer Ginger Baker – who wrote the lyrics – and British jazz pianist/composer Mike Taylor.

Tubeway Army’s “Are ‘Friends’ Electric” hit the top of the UK single’s chart in the last week of June 1979. It stayed there for four weeks. Its parent album, Replicas, lodged itself in the Top 75 for 31 weeks. In April, just as Replicas was out, Tubeway Army began recording demos for the next album: the band which had been assembled for the task debuted on BBC2’s The Old Grey Whistle Test on 22 May.

Manticore was owned by Emerson, Lake and Palmer and their manager. The organisation provided the name for the band’s label. Apart from ELP and its individual members, the best-known signees to the imprint were Italian prog-rockers PFM and former King Crimson member Pete Sinfield. Despite this new album’s title, Motörhead were not with Manticore.

Procol Harum’s “A Whiter Shade of Pale” was an instant phenomenon. Recorded in April 1967 and issued as a single on 12 May after pre-release play on pirate station Radio London, it topped the UK charts four weeks later. Globally, it hit big on most pop markets and was integral to launching the classical music/pop hybrid which evolved into prog rock.

“Theirs is truly rock in extremis, a précis of the youthful impetuosity and cathartic chaos at the heart of real rock ’n roll.”
