Some Queen FLAC shows on mediafire

I request FLAC on mediafire of:

- Chicago 7.12.1978
- Buenos Aires 28.02.1981
- London 13.05.1978 (at least White Queen, curious to hear the last performance of it)
- Philadelphia 23.11.1977

Thanks in advance for who uploads these shows.

BUMP :-)

My main request is Argentina 1981, but I would also appreciate the others. Thanks.
