Help to finish wd be appreciated.
39d Standing on two legs (7)- presumably this begins with BIPED?
53a - Flexible but easily broken when father leaves (5) I wondered if this could be SLIDE but I'm not sure why.
Also, 52a - Instrument commonly played in marching band 4,4.
I have DRUM for the second word. Should it be SIDE DRUM?
Thank you all, especially for the hints as to where the answers were arrived at.Glad to have finished, found that puzzle more difficult than the usual.
