Hallo,<br/><br/>Which is correct?<br/><br/><b>Between 1983-1991, the band line-up frequently <u>change</u></b><br/><br/>or<br/><br/><b>Between 1983-1991, the band line-up frequently <u>changes</u></b><br/><br/>I asume the correct answer is "changes", since the key word is "line-up" which is singular - but I'm not entirely sure.<br/><br/>Thank You!
