To chart the entire career span of The Carpenters is nearly impossible. We do know that early performances were usually held during the day and that the timbre of the music performed was quite different than it is today. Early instruments were made of stone or bone and the early sound was very much more percussive than the later scratchy sounds developed in the Middle East and finally "The Whine" perfected in North America and Japan. Early performances were much better attended and music historians suspect that indeed the early performances were much "more pure" without interest in high-tech gear and flashy stage effects.
