Just one day after pharmaceutical executive Martin Shkreli was ordered by a federal judge to give up his Wu Tang Clan Once Upon a Time in Shaolin album as part $7.4 million in restitution, fans are finding out some surprising information about the never before heard record.

In a video from 2014 posted by TMZ, Wu Tang member U-God revealed that pop goddess Cher appears on one the songs along with Redman. The confused interviewer asks how that unlikely collab came together, to which U-God vaguely responded, “I don’t even know either!” No other details about the pairing up was discussed.

Watch the clip below, as U-God also talks about the future Once Upon a Time in Shaolin.
