Lyrics
Below are the parts that can be heard in this episode.
 * There's a time in each year
 * That we always hold dear,
 * Good old summer time;
 * With the birds and the trees'es
 * And sweet scented breezes,
 * Good old summer time,
 * When you day's work is over
 * Then you are in clover,
 * And life is one beautiful rhyme.
 * In the good old summer time,
 * In the good old summer time,
 * Strolling thru' a shady lane
 * With your baby mine.
 * You hold her hand and she holds yours,
 * And that's a very good sign
 * That she's your tootsie wootsie
 * In the good, old summer time.
 * In the good, old summer time.
