Newly Deads Bride & Groom Skeleton Halloween Decor Y2K Non Working

Newly Deads Bride & Groom Skeleton Halloween Decor Non Working Measure approx 16" tall X 12" wide. The battery cover of the bride is missing. Eyes are supposed to light up and they are supposed to move to the tune "I Got You Babe." But I can't get it to work. Could be a simple fix but I don't know, selling as is for decor only.
