Coming to London
You might have to visit a few places to get everything you need.
For starters, I would suggest Phil Parker Limited.
They are likely to have all you need as far as cornet mouthpieces are concerned, all the usual makes plus a few you might not have heard of!
Might be worth a phone call if you need anything specific though.
They'll also have valve oil, mutes and gig bags etc.
I know they stock sheet music but I don't think any of it is brass band stuff so, again, why not give them a call.
They are at 106a Crawford Street, London, W1H 2HZ. Tel; 020 7486 8206.
It's about 3 minutes walk from Baker Street tube station.
For Salvation Army band and solo music then, of course, come to us, Salvationist Publishing & Supplies, 1 Tiverton Street, London SE1 6NT.
We are a 2 minute walk from Elephant & Castle station.
We also have our full range of brass band and related CD's on permanent display, a choice of well over 400 CD's in all.
Again, give us a call if you are looking for anything specific and we'll advise you if we have it or not.
