Sure, but you wouldn't really have to have extensive knowledge of "I Love Lucy" to write "Ricky." The song doesn't really make many specific jokes or references to the show. And with all of Al's other TV based songs, I think if I were a CBS executive, I wouldn't look at "Ricky" and think - "HEY! This guy must be a HUGE "I Love Lucy" fan! I would think - big deal - he did a song about "I Love Lucy," in addition to his songs about "Jeopardy," "The Brady Bunch," "The Tonight Show," "Beverly Hillbillies," and "Gilligan's Island."
Well, it wasn't as simple as THAT, obviously. Fact is, "I Love Lucy" was (and still is) such a HUGE Viacom title that an idea for an ancillary tie-in product like a CD of Ricky Ricardo's musical moments would've most likely been developed in-house, especially since Al's career was kinda on the rocks at the time. No matter how famous a watchmaker you are, you can't just march into Warner Bros. and suggest a new design for a Superman watch - they have to come to YOU, that's just how it works in big business.
All I'm saying is, the "Ricky" video might have been what attracted them to consider Al in the first place. Keep in mind, at the time, "Ricky" was (unless I'm very much mistaken) the only song ever written about "I Love Lucy" to hit the Billboard charts. Same with "Jeopardy," which received considerable attention from Merv Griffin, but no soundtrack CD could come out of THAT because Jeopardy doesn't have many musical numbers. (Shame, too - not many people know it, but Ken Jennings can dance like a mofo). And upon its release (before "Eat It" even, so he wasn't even a household name), "Ricky" received a nationally-televised compliment from a certain very famous redhead.
That's not to say Al didn't go through extensive interviews with the executives and the Arnaz/Ball estate, during which I'm sure he proved how well he knew his "Lucy" and musical expertise, both of which would obviously be crucial for such a job (by this time Al had started recording the "Deep End" originals, so his skill as a producer was provable). And only after THAT, they would have determined that he was the man for the job.
Just gonna stand there and watch me burn...that's alright because I like the way it hurts...
