The story goes that Daniel Johns wrote “silver” and “chair” on a piece of paper, intending to request “Sliver” by Nirvana and “Berlin Chair” by You Am I when he rang a radio station. He wrote “silver” by mistake or else they might be Sliverchair.
KISS had “Love Theme from KISS” on their first album.
The Yellow Balloon did the song “Yellow Balloon” on the album “The Yellow Balloon.” To top it off, the flip side of their single “Yellow Balloon” was “Noollab Wolley.”
But the champs are Focus, who had the song “Focus III” on the album “Focus III.” They also had the albums “In and Out of Focus,” “Mother Focus,” “Focus 8,” and “Focus on Focus,” and song titles “Focus II,” “Focus IV,” “Mother Focus,” and several others with “Focus” in the title. It’s just icing on the cake that their biggest hit rhymed with “focus.”
