British multi-instrumentalist Graham Bond may have been the first "rock" musician to record with a Mellotron, beginning in 1965. A year later, The Beatles used it prominently on their groundbreaking single "Strawberry Fields Forever" (recorded November-December 1966). However, it was Mike Pinder of the Moody Blues who brought the Mellotron to the forefront of popular music with the 1967 album Days of Future Passed in songs including "Nights in White Satin" and "Tuesday Afternoon". Pinder, who worked for Mellotron for 18 months before joining The Moody Blues, actually suggested to The Beatles that they use a Mellotron. Pinder made regular use of the instrument on The Moody Blues' studio albums from 1967 through 1971. Their 1972 album Seventh Sojourn employed the Mellotron's predecessor, the Chamberlin.?
