Thanks for the tips. No problem with the language (well, big problem, but not mine). I can't sing a bit, so just the tune needed. Found a lot of stuff on YouTube (thanks Kat) that I can probably imitate reasonably well (there's even one of a fellow on a train playing something that looks like a short scale banjo - very convenient). Now, I'm off to Google "Deben Bhattacharya" (thanks Jack).
