Who sang the 1973 song captain howdysome lyrics go no longer my best friend you been running on streets at night scaring them girls again read about it in paper heard radio?

The song you are referring to is "Captain Howdy" by the American rock band, Gentle Giant. Here are some of the lyrics:

No longer my best friend

You've been runnin' the streets at night

Scare them girls again

Read 'bout it in the paper

Heard you on the radio

Your eyes

I feel they bore right through my soul

Your eyes
