Little known (or maybe just not much remembered) tidbit....
before Karen Carpenter was the "star" of the brother sister duo... she was just the drummer.

From Wiki:
Apart from being a singer, Karen was also an accomplished drummer, and often played the drums on their pre-1974 songs. According to Richard, she considered herself a "drummer who sang". Karen was rarely visible behind the drums during live performances. Although unwilling, she and Richard eventually reached a performance compromise: during the ballads she would sing standing and through the lesser known songs she would sit. As the years progressed, demand for Karen's vocals began to overshadow her drumming time, and gradually she played the drums less. By the A Kind of Hush album in 1976, Karen did not play the drums at all.
