About the article "Hey Jude", section "Personnel".

Candidate passages:
After the name change to Tinkerbells Fairydust, it recorded the single "Lazy Day", produced by Vic Smith, who went on to produce The Jam and Black Sabbath.
It never had any chart success in the UK.
It did, however, make the charts in Japan where "Lazy Day" reached number two (held off the top spot by The Beatles' "Hey Jude").
Its second single, "Twenty Ten", was a Bach-inspired minor key piece of harmony psychedelia, with wah-wah vox organ, mellotron flutes, Spanish style guitar, and choir-like vocals.
The lyrics alluded to the year 2010 which was still 43 years away in 1967.
Despite finding favour with the BBC Radio DJ John Peel, it was a commercial flop.
Its third single, "Sheila's Back In Town", was released in January 1969 in the UK.
It made the Top 10 in Japan. 
Allman's playing on the two Hour Glass albums and an Hour Glass session in early 1968 at FAME Studios in Muscle Shoals, Alabama had caught the ear of Rick Hall, owner of FAME.
In November 1968 Hall hired Allman to play on an album with Wilson Pickett.
Allman's work on that album, "Hey Jude" (1968), got him hired as a full-time session musician at Muscle Shoals and brought him to the attention of a number of other musicians, such as Eric Clapton, who later said, "I remember hearing Wilson Pickett's 'Hey Jude' and just being astounded by the lead break at the end.
I had to know who that was immediately—right now.
"Allman's performance on "Hey Jude" blew away Atlantic Records producer and executive Jerry Wexler when Hall played it over the phone for him.
Wexler immediately bought Allman's recording contract from Hall and wanted to use him on sessions with all sorts of Atlantic R&B artists.
While at Muscle Shoals, Allman was featured on releases by a number of artists, including Clarence Carter, King Curtis, Aretha Franklin, Laura Nyro, Wilson Pickett, Otis Rush, Percy Sledge, Johnny Jenkins, Boz Scaggs, Delaney & Bonnie and jazz flautist Herbie Mann.
Shortly after he recorded the lead break in "Hey Jude", he recorded all of the lead guitar in Boz Scaggs' "Loan Me a Dime".
