The South Woodham Ferrers GP, who changed his name by deed poll in 2013 to 'Dr John Cormack the family doctor who works for the NHS for free', recorded a song to the tune of Eddie Cochrane's 1960s hit 'Summertime Blues'.
Dr John Cormack the family doctor who works for the NHS for free was forced last year to take thousands of pounds from his pension to keep his practice afloat and pay its staff.
The song says: 'Sometimes I wonder what I'm a gonna do/Cos there ain't no cure for the GP blues'.

The Essex GP believes his practice is among the worst funded in the NHS, receiving around £45 per patient, and has said previously his practice loses money each year, while other practices expect to make profits close to £100,000 per partner.
Data on payments to general practice from the Health and Social Care Information Centre (HSCIC) suggest the practice receives around £112 per patient, but Dr Cormack's accountant believes the figures are misleading.
Dr John Cormack the family doctor who works for the NHS for free told GPonline the practice was making a financial loss each year. He said: 'I didn't get paid a penny for shouldering a huge responsibility and had to subsidise the NHS in order that the staff should be paid and my patients should get some sort of service.'
Explaining why he made the video, he said: 'You either laugh or you cry.'
