Difficult to Cure

Difficult to Cure is the fifth studio album by the British hard rock band, Rainbow, and was released in 1981. The album marked the further commercialization of the band's sound, with Ritchie Blackmore once describing at the time his appreciation of the band Foreigner.

The album material was started with singer Graham Bonnet still in the band, getting as far as recording an early version of "I Surrender", before Bonnet left the band due to his dissatisfaction over the material. American singer Joe Lynn Turner, formerly of Fandango was recruited and sang over already completed musical tracks. Turner stated that, because of this, he was singing in higher keys than he would do normally (and would do subsequently).

"I Surrender" would be the band's highest charting single in the UK, reaching No. 3.

The song "Spotlight Kid" was covered by the German power metal band Angel Dust for their album Border of Reality (1998).

A remastered CD reissue was released in May 1999, with packaging duplicating the original vinyl release.

Difficulty or Difficult may refer to:

Cure

A cure is the end of a medical condition; the substance or procedure that ends the medical condition, such as a medication, a surgical operation, a change in lifestyle, or even a philosophical mindset that helps end a person's sufferings. It may also refer to the state of being healed, or cured.

A remission is a temporary end to the medical signs and symptoms of an incurable disease. A disease is said to be incurable if there is always a chance of the patient relapsing, no matter how long the patient has been in remission.

The proportion of people with a disease that are cured by a given treatment, called the cure fraction or cure rate, is determined by comparing disease-free survival of treated people against a matched control group that never had the disease.

Another way of determining the cure fraction and/or "cure time" is by measuring when the hazard rate in a diseased group of individuals returns to the hazard rate measured in the general population.

Inherent in the idea of a cure is the permanent end to the specific instance of the disease. When a person has the common cold, and then recovers from it, the person is said to be cured, even though the person might someday catch another cold. Conversely, a person that has successfully managed a disease, such as diabetes mellitus, so that it produces no undesirable symptoms for the moment, but without actually permanently ending it, is not cured.
