ZZ Top's electric guitar player surprised fans of the rock group last week by travelling to a gig in London on the Tube.
The rock group were gearing up for a gig at Wembley Arena when Billy Gibbons decided to purchase a ticket for the London Underground.
Speaking to BBC News, he revealed that he did feel a "little edgy" at first on the train, as one man on the route was "checking me out".
"And then I realised that he was looking at a ZZ Top concert ticket," Gibbons commented.
The bearded musician added that he may keep taking public transport to gigs, as he arrived at the venue before his bandmates.
This is despite the fact that the Circle Line broke down only minutes after he purchased his train ticket.
ZZ Top formed in the 1960s and have since notched up numerous worldwide hits such as Sharp Dressed Man, La Grange, Viva Las Vegas and Legs.
