A court has heard a former South Australian music teacher and paedophile will likely die in jail.
The 80-year-old has already been sentenced to more than a decade behind bars and has now admitted to more crimes against another of his students.
Two years ago former South Australian teacher Malcolm Day was jailed for repeatedly preying on one of his pupils.

Now, another student has come forward.
Day should have been teaching the talented teen music but instead, he has pleaded guilty to grooming and abusing the 15-year-old in the early 1980s, years before the crimes for which he is already serving 12 years.
The decades-long impact of his predation was revealed in a powerful victim impact statement, calling for him to be handed at least 10 years jail on top of time he's already serving in prison, where his lawyer concedes the now 80-year-old will likely die.

"Well that's a real prospect isn't it… given his age," defence lawyer Stephen Ey said.
The statement said Day's "selfish and disgraceful conduct" changed the survivor's life.
"He poisoned my future for his own pleasure and went on to lie about it," the statement said.
Day had written a letter of apology but his lawyer chose not to read it out loud in court, the judge suggesting it revealed he still lacks insight into his offending.
The court heard his old age shouldn't be taken into account, because "he's had the benefit of living… his best years as a free man."
