"I Left My Heart in Cincinnati" was Danny Bonaduce's favorite episode, and it's no surprise, as the setting is the famous Kings Island outside Cincinnati, featuring a short bit from Reds catcher and World Series slugger Johnny Bench. The Partridge Family is spending a week at the summer resort, all expenses paid as well as performing, but when Keith meets public relations director Audrey Parson (former Miss America Mary Ann Mobley), it's a clear case of head over heels. Attempts to impress her on the diving board go awry (Shirley: "you don't belly flop for just anybody!"), and his next try at a date winds up shared with Danny, who also proclaims his love for Audrey. It seems she's only safe with Chris, offering to take her to see "Dracula Bites the World!" (even Reuben strikes out). The main song starts things off, "Girl, You Make My Day," composed by Tommy Boyce and Bobby Hart, apparently the only track recorded from the very duo that provided so many familiar Monkees hits (taken from fifth LP SHOPPING BAG, and seemingly never issued by anyone else). We also get a reprise of "Together We're Better," composed by Tony Romeo and Ken Jacobson, previously heard in "Princess and the Partridge" (from sixth LP NOTEBOOK). Those familiar with Kings Island will also remember The Banana Splits and their lone hit, "The Tra La La Song (One Banana, Two Banana)," which only reached number 96 on the Billboard singles charts in Jan 1969; THE BRADY BUNCH would also go to King's Island in 1973.
