Quick Q: Can you name a chord like CMaj7add9? I mean, it's a root, third, fifth, 7th and a 9th. And/or can/do you call it CMaj79? Thought of this chord when seeing the C69 chord (R,1,3,5,6,9). Just curious what the "correct" name is for this chord or if you can call it whatever you like (using the word 'whatever' lightly here).

Oh yeah, another Q. Seen that some write like C6/9 instead of C69. To me that would indicate that the 9 would be the bass a la the term Slash-chord. What are your thoughts and who's treating me to some grilled chicken with lots of booze tonight?
