The 'Flower' singer was scheduled to sing 'Especially For You' with Donovan for the first time in years at the PWL Hit Factory concert back in July, but it was cancelled due to bad weather conditions.
The concert has now been rearranged for London's O2 Arena on December 21, but Minogue is yet to be confirmed in the lineup.
Speaking about the axed show, Minogue told the Daily Star: "I really felt for people when it was cancelled; it was so touching, the level of excitement. I was like: 'Oh, someone's gone and got a bubble perm and [they] are all ready to go.'
"We did the rehearsal two days before and Jason and I looked at each other and realised we had never done ['Especially For You'] live as it was released back in the mime days of Top of the Pops.
"We have actually done it live three times in rehearsals, but that's it."
Minogue said that if her schedule permits, she will attend the December gig, saying: "They've revamped the show and I've said: 'If I'm available, I'll be there.' If it doesn't happen now, it'll be something to look forward to.
"My schedule to the end of the year is making me cross-eyed - I'm all over the place."
Minogue will release a new collection of reworked material - The Abbey Road Sessions - on October 29. Watch the video for her new single 'Flower' below:
