### Instruction: When was "I'm Just a Singer (In a Rock and Roll Band)" released?
### Input: "I'm Just a Singer (In a Rock and Roll Band)" is a 1973 hit single by the English progressive rock band the Moody Blues, written by the band's bassist, John Lodge. It was first released in 1972 as the final track on the album Seventh Sojourn and was later released as a single in 1973, with "For My Lady" as its B-side. It was the second single released from Seventh Sojourn, with the first being "Isn't Life Strange", which was also written by Lodge.

The song reached number 12 on the Billboard Hot 100 in the US, becoming one of their highest-charting hits in that country, but fared less well in their native UK, where it managed number 36. It was also the final single released by the Moody Blues prior to their five-year hiatus, which was agreed upon so each of the band members could pursue their own solo careers. Their next single would not be until 1978, with "Steppin' in a Slide Zone".
