Men of Harlech?
Of course! But since the current Welsh Regiment was formed from the Royal Welch Fusiliers, the Royal Regiment Wales and The Royal Welsh Regiment (TA), the present organization shares the regimental hiustories of both The Welsh Regiment and the previous Royal Welsh Fusiliers, Sousa's Royal Welch Fusiliers march [Mr. Sousa's spelling, not mine!] is also most appropriate, since it was written to commerate the bond between Welsh Fusiliers and U.S. Marines formed during their service together during the *Boxer Rebellion* in China.
