there is a similarity,between Sweet Thames and Recriuted ColLier,apart from them both having good lyrics.
I find it impossible to sing one after the other,without confusing the tunes,the first parts are almost identical.
I have the same problem with a couple of hornpipes Fairies and Off to California.
