The Ask Science Mike theme song was written, performed, and recorded by Jeb Bodiford. If you need original podcast music, he's your guy.
You've got questions, he's got answers.
Even though we may not understand he'll talk anyway.
You've got problems, he won't solve them,
But he'll talk and talk and talk until he's blue in the face.
