In the early summer of 2004, when Pete Doherty once again found himself cast out of The Libertines because of his drug use,[1] he brought Babyshambles to the fore with Walden on lead guitar.

The band's line-up underwent several changes before stabilizing during the late summer of 2004 with Doherty on vocals, Patrick Walden on guitar, Gemma Clarke on drums and Drew McConnell on bass.

Other Doherty/Walden compositions include Top-10 single "Fuck Forever" and "Loyalty Song," "352 Days," "In Love With a Feeling," "Up the Morning," "Pipe Down," "32 December," and "8 Dead Boys."

Often citing experimental guitarists like J Mascis, Thurston Moore and Jimi Hendrix as early influences, Walden's unusual playing style set Babyshambles apart from other bands in the East London music scene.

[5][6] Walden was rumoured to have been playing at The Cheltenham Jazz Festival (27 April–2 May) as a special guest with Seb Rochford's band Fulborn Teversham, but cancelled the appearance.

The set list included "The Man Who came To Stay" and "8 Dead Boys" On 3 August 2007, Walden played a small gig in Hackney with all of his former Babyshambles bandmates (as well as Mick Whitnall) for friend Peter Wolfe's birthday.

After being spotted acting suspiciously in a Sutton branch of Wilkinsons, Walden was pursued by security who found in his possession stolen goods and Methodone prescribed to another user.

In November 2014 Walden did his first interview and photoshoot in a number of years with friend, music enthusiast and blogger, Olivia Collins for the website www.themusicalacidtest.com and photographer, Jack Grange.
