The Sweet Stuff Foundation was founded in 2013, and now rockers including Josh Homme have clubbed together to rejuvenate the organisation for performers with serious illnesses and disabilities.

Bosses at the foundation are auctioning off various items, including a signed guitar from last year's (14) Grammy Awards, over the coming months.

A statement from the charity reads, "The mission of The Sweet Stuff Foundation is to help our musical community and their families with the vital elements often overlooked during periods of illness and disability. Things like transportation to medical treatment, assistance with childcare and tuition, income assistance, the 'last wishes' of a lifetime, and special treatments not covered by insurance.

"The healing power of music is also a vital form of preventative medicine. That's why the Sweet Stuff Foundation's two prong approach is also committed to providing assistance for music lessons, instruments, and musical collaborations for children."
