Paul McCartney & Wings | Old Siam, Sir | Back to the Egg
“Old Siam, Sir” is a hard rock single from Wings’ 1979 album, Back to the Egg. It was the A-side of the UK version of the single, reaching No. 35. The B-side in the UK was also a track from the album, “Spin it On”. “Old Siam, Sir” was also the B-side of the US single “Arrow Through Me”.
