I'm trying to understand what does this sentence mean:
Hey, Johnny Holiday just laid on you another triple-golden sweep from golden-weekend time at KXLA, in Ames, lowa.
This sentence is said on the radio without any further context around it. I've tried to gather some information and found out that Johnny Holiday is a vocalist. Except for that this sentence doesn't make much sense to me (I'm not a native speaker) in any of its parts. I know this is a pretty broad question, could you please enlighten me on the possible meaning of it? Expecially the "laid on you a sweep" part.
Thanks in advance!
