The announcement of a new Blacksburg and New River Valley ukulele get together reminds me to tell ukulele playing friends that they will not necessarily be met with scorn and derision if they show up at other jam sessions in the area, as long as they learn some traditional old time string band tunes.
In fact, ukes have been infiltrating old time music since John Hopkins' loud and clear in the original "Hill Billies," 1926:
Blue Ridge Mountain Blues - The Hill Billies 1926!
"Al Hopkins ... was the leader of his own band called the Hill Billies (also known as the Buckle Busters). The band members consisted of Al Hopkins (piano), John Hopkins (ukulele), Joe Hopkins (guitar), John Rector (banjo), and Tony Alderman (fiddle).
"The Hill Billies had been discovered by Ralph Peer a year earlier and had made some records for Okeh (a forerunner of Columbia). When Ralph Peer asked Al Hopkins the name of his band, Al responded “We ain’t nothing but a bunch of hillbillies from North Carolina and Virginia. You can just call us anything.” Mr. Peer appropriately named them the “Hill Billies”.
