LIGHTHOUSE - SUMMER DAYS , Hardly my favorite , but it gets the laziness vibe down pat.
Troggs - Summertime (Not "When the gIrls wear the dresses so low....wish you were here , The Miller Beer Ads. ) , I'LL BUY YOU AN ISLAND , and yes , SUMMERTIME (YOU CAN SEE THE SUN ON THEIR T-T-T-T-T-T-TANNED SKIN.....).
Mungo Jerry - In The Summertime (Of course. Back when singing about drinking and driving and taking advantage of rich and poor girls aliKE could land you an international top ten).
Hanoi Rocks - Malibu Beach Nightmare (No too takin' er easy , but , the perfect summer song.).
