Can the melody of one hit record be the inspiration for another? Apparently, yes, as “You Didn’t Have to Be So Nice” by the Lovin Spoonful was the inspiration Brian Wilson used to write the Beach Boys classic, “God Only Knows.” Released on Kama Sutra Records in 1965, the 45 is worth up to $50.00 with its picture sleeve UNLESS it’s a promo copy as seen here. Then the value jumps to $200.00 even without the picture sleeve. 

Find the values for all promo records that are worth more than the commercial versions released in stores with “Mighty John’s Promo Records Guide,” available in the yellow strip above.)
