Song, an unraced 3-year-old filly by Sadler's Wells, sold for 1.7 million guineas, or almost $3 million, on Tuesday to top the second session of the Tattersalls December mare sale, according to sales results.\nIn foal to Danehill Dancer, Song is out of the Darshaan mare Jude and is a half-sister to two Group 1 winners, 2003 Irish 1000 Guineas winner Yesterday and 2001 Moyglare Stud Stakes winner Quarter Moon, the champion 2-year-old filly in Ireland that year. Song was bought by Badgers Bloodstock and consigned by Bugley Stud.\nThe price paid for Song established her as the highest-priced lot to sell so far at the most prominent bloodstock sale in Europe.\nFor the first two days of four days of selling, 333 horses have gone through the ring for a total of approximately $45.4 million at the current exchange rate.
