This is a great old jazz tune from 1951 by George Shearing, who was British. He was considered one of the greatest jazz pianists of his time and all time This is his most famous and enduring song, Lullaby of Birdland. It was written in honor of Charlie "Yardbird" Parker, the founder of the Birdland Jazz Club. It's often played instrumentally, even though it has very cool and nifty lyrics written by George Weiss. That's because jazz musicians love to improvise on the very versatile melody. You also often hear it played instrumentally in movies as a musical marker for the mid-20th century. This song creates the mood of the late 40s/early 50s, and no song does it better. Cool then; cool now; and forever cool: this is Lullaby of Birdland.
