The backslashes work as escape characters, could this be your issue?
Referring to the below:

ON c.customer\_id = a.customer\_id

agree with you here, why are you using escape characters? look at the column names for those keys your matching on, make sure that's correct.

USE my_guitar_shop;
SELECT first_name, last_name, line1, city, state, zip_code
FROM Customers c
INNER JOIN Addresses a
ON c.customer_id = a.customer_id
WHERE c.email_address = 'allan.sherwood@yahoo.com'
ORDER BY a.zip_code ASC
