"I'll Be Gone" or "Some Day I'll Have Money" is a song by Australian progressive rock group Spectrum released as their debut single by EMI on Harvest Records in January 1971.

[2] Spectrum was formed in Melbourne in 1969 by Mike Rudd, a New Zealand-born singer, songwriter and guitarist (ex-Chants R&B, The Party Machine, Sons of the Vegetal Mother), together with bassist Bill Putt (Gallery, The Lost Souls), organist Lee Neale (ex-Nineteen 87), and drummer Mark Kennedy.

[1] Spectrum played covers of Traffic, Soft Machine and Pink Floyd initially, they then developed their own style and wrote a set of original material.

[1] One side was an early, folky version of "I'll Be Gone", according to rock historian Ian McFarlane, these acetates are now "impossibly rare" and only two or three copies are known to have survived.

[4] Chris Löfvén went on to direct the video for Daddy Cool's debut single "Eagle Rock" which also peaked at #1 later in 1971.

[5] Several cover versions of "I'll Be Gone" have been recorded by artists including Colleen Hewett, Margret RoadKnight and Manfred Mann's Earth Band.

[6] In May 2001 the Australasian Performing Right Association (APRA), as part of its 75th Anniversary celebrations, named "I'll Be Gone" as one of the Top 30 Australian songs of all time.
