This one is for those of you that enjoyed the earlier post of Greg Pattillo - the flute playing human beatboxer.
Here he is again, but this time accompanied by M.C. Dapper D freestyling live on the streets of Boston.
Also, it gives me an excuse to post this excellent picture (to the right) of Ian Anderson from Jethro Tull.
Now swap the flute for bagpipes and you've got Billy Connolly.
