This is probably one guy who makes compilations and digitalizes concert tapes. These are the Salamander releases I'm familiar with: (I'm looking for Wings's Nottingham concert 1972 on this label so if anyone has it: I'm ready for a trade! - I've only got a bad copy...)
George Harrison - Only A Dream Away (1 CD-R, SCD 1002)
George Harrison - San Francisco 1974 (1 CD-R, SCD 1015)
Paul McCartney - Let Me Roll It To Boulder (3 CD-Rs, SCD 1022/24)
Ringo Starr - All Dried Up (3 CD-Rs. SCD 1111/13)
