Tich Gwilym (1951 – 19 June 2005), born Robert Gilliam, was a Welsh rock guitarist who was most notable for his Hendrix inspired version of the Welsh national anthem, Hen Wlad Fy Nhadau, considered one of the most famous renditions of the song.
Gwilym was born in Penygraig, in the Rhondda Valley in 1951. One of Gwilym's earliest bands was Kimla Taz, who he played with during the late 1960s. Although the band never gained any mainstream success, they were popular in South Wales and in 1969 played at the Croeso '69 Blues Festival at Abergavenny, alongside the likes of Fleetwood Mac and Jethro Tull.
Gwilym found fame in the 1970s, when as part of Geraint Jarman a'r Cynganeddwyr, he recorded the Welsh national anthem on the electric guitar. The Jimi Hendrix inspired version, which first appeared on Jarman's 1978 album also called Hen Wlad Fy Nhadau, became synonymous with Gwilym and has appeared on compilation albums of Welsh artists. In 2006, an eight track recording of the Welsh national anthem was 'discovered' in London. At the time it was alleged that this was a lost version by Hendrix, though others claimed that it was a rendition by Gwilym. When approached, ex-band member Geraint Jarman dismissed both claims, stating that 'It's definitely not Tich because his style was more like Hendrix's than the actual tape'. It was later discovered that the version was a hoax, perpetrated by record producer Martin Davies and ex-guitarist of The Vibrators, John Ellis.
