Zappa parodied Frampton's song "I'm in you" as "I Have Been In You". A radio spot (which may or may not reach the airwaves) was taped for the LP, featuring Frampton himself talking over said song. "Hi, Frank," the English teen idol begins, rather nervously. "This is Peter here. I'd just like to correct you on the words. It's 'I'm in you, you are in me.' Umm, there's not too much that I can say about this ... uh, I've never really liked your music, and I don't really like this. But, if you'd had me on rhythm guitar, it would've been a hit."
