Light Up Lyrics

The obvious play to marijuana is and was evident back then ('75). The middle section also deals with physical love:

Every day's a holiday when your lips meet mine The music's keepin' time with our love You are here, and so am I The weather's quite divine So pass me round your wine, lovely one

It's pretty blatant what the singer wants from his love here.
