I thought I would leave this for the benefit of others who may be trying to setup CNAME records. Here are some CNAME records I have setup on my new (experimental) DNS server, ns1.topsecret.com (I have swapped out the domain name and IP addresses, but these are real examples from real queries).
topsecret.com. IN SOA ns1.topsecret.com. secure.topsecret.com. 2020060102 7200 3600 1209600 3600
topsecret.com. IN A 111.222.333.44
ns1.topsecret.com. IN A 111.222.333.44
ns2.topsecret.com. IN A 55.77.88.99
demo1.topsecret.com. IN A 111.222.333.44
demo2.topsecret.com. 120 IN A 55.77.88.99
www.demo1 IN CNAME demo1
www.demo2 IN CNAME demo2
www IN CNAME topsecret.com.
Here are some dig responses:

topsecret.com. 0 IN A 111.222.333.44
This is what you would expect.
Note, the 120 in the response for www.demo2.topsecret.com, as I have set the TTL to 120 for that particular record. Since the TTL is not set for the others, it returns 0.
Triple warning! In order to get this post to post properly, I had to swap out all of the "www"s and replaced them with "www" as otherwise this editor will actually strip them all out, and render them without the "www"!
