1) One person has a nickname that starts with the same letter as the color of his sax. Another has a nickname that starts with the same letter as the type of sax he has.

2) Heatwave, the tenor sax player, often plays duets with Aaron.

3) Randy's sax and the blue sax are both altos.

4) The gold sax is smaller (or higher) than Leon's and bigger (or lower) than the red one.

5) Polar Bear got his nickname because his sax color and his white beard remind the others of the arctic ice and snow.
