Absolutely, i liked Jethro Tull a lot, they definitely brang someting different but familiar too Rock n Roll! Men At Work also used a flute in many of their songs and worked out great! Buddy Holly, in the beginning was ridiculed for the things he tried (ex. Using a symphony orchestra in conjunction with your "standard" rock n roll band instruments (guitar, bass, rhythm guitar, and drums) . As you say, Jethro Tull's influence is great and quite unique. Plus they're just badass to begin with! :)
