South Woodham Ferrers GP Dr John Cormack, who has also changed his name by deed poll to 'Dr John Cormack the family doctor who works for the NHS for free' to publicise his practice's plight, recorded the song last month.
A video posted on YouTube by the GP opens with a spoof conversation with his bank manager.
'Hello, bank manager,' says Dr Cormack. 'What? The NHS fat cats haven't given me enough moolah to run my practice?'
Dr Cormack then launches into a reworked version of 'Sweet Nuthin' - a 1970 Velvet Underground track - spelling out why his practice is in trouble. Through the video, the Essex GP poses in mocked-up scenes with his bank manager, patients and practice staff, singing lines such as: 'I been working 40 years, for mmmm, sweet nothing/General practice cost me dear, I got mmmm, sweet nothing.'
The Greenwood Surgery GP's song is his latest attempt to draw attention to severe underfunding at the practice, which he says has the lowest doctor-patient ratio in the Mid Essex CCG area.
GPonline has reported on huge variations in GP funding across England - with practices in some CCG areas receiving on average around twice the amount that practices in other CCG areas receive.
This website has also reported on patients' crowdfunding efforts to keep Dr Cormack's surgery going, and the GP's decision to raid his own pension fund to help maintain patient services.
Dr Cormack told GPonline: 'We have applied for additional funding for caring for our existing patients -we were given a small amount of additional funding for six months for taking on a share of the patients from a nearby practice that is closing, but "sweet nuthin" for looking after our existing patients this year or next.'
Dr Cormack says a request from his practice for extra funding under the vulnerable practices scheme was turned down.
