Feel awash with festive nostalgia with two Christmas tunes from Say She She on a must-have 45 this holiday season.  On the A, gentle voices drift and float above tumbling chromatic piano lines that fall like moody Purple Snowflakes in Say She She's cover of this quintessential psychedelic Christmas classic - originally by Marvin Gaye.   The B-side is Say She She's first original Christmas song. 'This Wintertime' is a heartfelt carroll composed with love, nostalgia and a room full of kin. The track serves as a reminder that perhaps the greatest gift of all to give during the season is in fact simply a sweet song and to let music will make us merry.
