(1971)

The soulful track "Lieutenant (Had Any Lately?)" (Stang Records # ST-5027), out of New Jersey, took an anti-war line and condemned Calley - one of the few to do so.

Is this record performed by Sylvia Robinson?

A year earlier she released the single Have You Had Any Lately (Stang # 5015) - the same melody and with almost identical lyrics, without the Calley references, written by Robinson.
(1) Robinson did in fact have three children.
(2) The song later appeared on the 1973 album Pillow Talk (Vibration Records # VI-126).

Anyhow, the structure of the verses, formed by repeating questions ('how long' and 'how many') took a similarly effective approach to Bob Dylan's "Blowin' in the Wind" - the narrator wanted to know "how many children did you kill" and "how much...of their blood did you spill". She declared that Calley's actions made him "inhuman" and "not fit for society".
