You could use one of Uncle Stavro's esoteric show concepts for the 15th if you wanted.

It's called "Show Of The Dead", a show full of dementia tunes made entirely by artists who are now dead. If the show that follows is Xmas in July, you can have Halloween in July also. It won't actually be about Halloween, just about artists who no longer exist.

Also let me know what subject you want for the July 15 show.

Note: The July 8 show will be posted late Monday night due to the 4th of July holiday.
