After all of the hullaballoo surround His birthday, its high time Jesus got to kick back, relax and enjoy the festivities of someone else's birthday, like, say, the Pikes Peak Jazz and Swing Society. Over 40 musicians will take over the Flying W Ranch Saturday and Sunday to celebrate the Society's 15th birthday. Ragtime, swing, jazz, salsa and big band will fill the air during dances, dinners and cake walks. Saturday's activities begin at 1:45 and require reservations. Admission is $24. Sunday is open to all beginning at 1:45 p.m. and costs $10. Two-day packages are $30. Call 684-2429 for more.
