"For a 40th birthday in Austin, consider 'Don't Stop Believin'' by Journey to evoke nostalgic memories, or 'Crazy Little Thing Called Love' by Queen for a fun, energetic vibe."
"Arrange photos chronologically, starting with baby pictures, moving through school years, career milestones, family moments, and ending with recent celebrations at a venue like The Highball."
"Ask family and friends to record short voice clips sharing their favorite memory of the celebrant, or a funny anecdote from one of their 40 years. For example, 'I remember when Sarah tried to bake a 5-tier cake for her 30th – it was a delicious disaster!'"
