Summer is definitely here. Two days of 78 degrees!
Real signal: the ice-cream man is making his first rounds of the year. Instead of the Official Ice Cream Man Music (Entertainer Rag), his music machine is playing La Curaracha. Rather nice arrangement, full verse and chorus.
Intended to appeal to Hispanics? Or to pot smokers? More likely the latter. But .... is it wise to associate cucarachas with ice cream?
